Have millions or even billions of people around the world suddenly disappeared all at once, in the blink of an eye? Even perhaps including some of your friends and family?
Is the world full of fear, confusion, and chaos as a result?
Are the world's leading experts claiming that it was a mass abduction by aliens? Or maybe some shift into a new era or dimension of consciousness?
If so, I want to reassure you that no, it wasn't. And all those people who disappeared are completely safe.
In fact, they're now happier than they have ever been in their entire lives. You don't need to worry about them.
In this post below, I'll explain what has happened, what it means, and what you need to know for your immediate future, because things are about to become very dangerous for everyone who has been left behind on Earth.
Where Did All The Missing People Go?
This event, although it has been shocking to you, has actually been known about for just a little less than two thousand years. You've probably even heard it mentioned before.
It's called the Rapture, and it's described in the Bible:
For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord (1 Thessalonians 4:16-17).
At the exact same moment, God changed the bodies of the people who disappeared from mortal to immortal:
Behold! I tell you a mystery. We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed. For this perishable body must put on the imperishable, and this mortal body must put on immortality (1 Corinthians 15:51-53).
After everyone who was raptured met Jesus in the clouds, we went from there to heaven, where Jesus has been preparing places for us to stay with him. Jesus said:
Let not your hearts be troubled. Believe in God; believe also in me. In my Father's house are many rooms. If it were not so, would I have told you that I go to prepare a place for you? And if I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also (John 14:1-3).
So that's what just happened. Everybody who suddenly disappeared had, at some point in their lives, believed that Jesus Christ had died for their sins so that they could have the free gift of eternal life:
For God so loved the world that he gave his only Son, so that everyone who believes in him may not perish but may have eternal life. Indeed, God did not send the Son into the world to condemn the world, but in order that the world might be saved through him. Those who believe in him are not condemned; but those who do not believe are condemned already, because they have not believed in the name of the only Son of God (John 3:16-18, NRSVA).
If all or at least some children have suddenly disappeared also, it is because they fit into one of two categories:
- They were old enough to have personally believed in Jesus, and did so.
- They were too young to have personally believed in Jesus, or were older but mentally incapable of doing so. But God, in his love and mercy, chose to spare them from having to experience the terrible events that will be occurring on Earth over the next several years.
I believe this second category will definitely include the young children of Christian parents, since God wouldn't rapture the parents and leave their helpless children behind. But it could potentially include all children who were not yet old enough to have personally rejected Jesus' offer of salvation, since we know that Jesus loves children very much (Matthew 19:13-15, Matthew 18:1-6).
There is no specific age cutoff given in the Bible for children in relation to the Rapture. Some scholars argue that the age at which God counts people to be personally responsible for their beliefs may even be as high as twenty, based on Numbers 32:11, as well as modern scientific studies which suggest that a person's brain is only fully developed around that age. If so, it is possible that perhaps everyone who is under twenty years old may be taken to heaven in the Rapture.
The concept of the Rapture has been mocked for many years (2 Peter 3:3-4), despite there being several convincing Biblical arguments for it. Even now, authority figures and other experts of various sorts (maybe even some pastors and priests) are probably telling you that whatever just happened wasn't the Rapture.
But hopefully, if everything has happened as described above, this will convince you that the Bible is true and that Christians who warned about the coming Rapture were telling you the truth.
And if you believe that the Rapture did just happen, then you will hopefully care about what else the Bible says will happen in the next few years. Christians who have studied Bible prophecy refer to this upcoming period of time as the Tribulation.
What Do The Rapture And The Tribulation Mean?
If you missed the Rapture, the good news is that there's still time for you to believe in Jesus as your savior.
However, you will be heading into the Tribulation.
Jesus warned that during the Tribulation,
This will be the worst time of suffering since the beginning of the world, and nothing this terrible will ever happen again. If God doesn't make the time shorter, no one will be left alive. But because of God's chosen ones, he will make the time shorter (Matthew 24:21-22, CEV).
The Tribulation includes all the events that will occur as described in chapters 6 to 19 of the Biblical book of Revelation.
It ends with the second coming of Jesus Christ, along with his heavenly armies of saints and angels. Jesus will destroy the armies of the world who will make one last-ditch attempt to oppose him, and Jesus will then set up his kingdom that will last for 1000 years (Revelation 19:11-21, Jude 1:14-15, Revelation 20:1-6).
There may be some period of time between when the Rapture occurs and when the Tribulation starts. This gap could be perhaps as long as weeks, months, or even a year or two, because it will take some time for the world to get reorganized and deal with the chaos the Rapture caused. But I don't think the gap will be decades.
That's because the purpose of the Rapture was to prevent all true Christians (and perhaps all children) from experiencing God's wrath, which will be poured out on all the God-rejecting people who were left behind on Earth.
Jesus promised all true Christians who live before the Rapture that "I will protect you from the great time of testing that will come upon the whole world to test those who belong to this world" (Revelation 3:10, NLT).
God also promised, through the Apostle Paul's writings, that Christians who believed in Jesus before the Rapture would not experience God's wrath and judgment, which would come on the world suddenly and surprise everyone who wasn't paying attention:
For you yourselves know very well that the day of the Lord will come like a thief in the night. When they say, "There is peace and security", then sudden destruction will come upon them, as labour pains come upon a pregnant woman, and there will be no escape! But you, beloved, are not in darkness, for that day to surprise you like a thief; for you are all children of light and children of the day; we are not of the night or of darkness... For God has destined us not for wrath but for obtaining salvation through our Lord Jesus Christ, who died for us, so that whether we are awake or asleep we may live with him (1 Thessalonians 5:2-10, NRSVA).
Christians who studied Bible prophecy and paid attention to current events have warned for many decades that the world is approaching the Tribulation. We could see the signs of the end times increasing in frequency and intensity, just like contractions do for a pregnant woman in labor, as mentioned in the verse above. But this was only the lead-up to the Tribulation.
Whenever the Rapture happens, afterward, there will no longer be a single true believer in Jesus left on the planet. This makes the world ready for God's testing and divine judgment.
Therefore, I believe the events of the Tribulation will begin quite quickly after the Rapture.
What Will Happen During the Tribulation?
The Tribulation will involve God sending twenty-one specific divine judgments on the world. These judgments are grouped into three sets, and are represented symbolically as Jesus opening the seals on a scroll, as angels blowing trumpets, or as angels pouring out bowls of divine wrath onto the world.
Here is a very brief summary of these future judgments:
The 7 Seals
- Seal 1: The revelation of the Antichrist, a.k.a. "the Beast" (Revelation 6:1-2, 2 Thessalonians 2:3). There is more information about him later in this post, to help you identify him when he appears.
- Seal 2: Outbreak of worldwide wars and violence (Revelation 6:3-4, Matthew 24:6, Matthew 24:12).
- Seal 3: Some sort of economic disaster and/or severe famine, which means that for most people, a day's wage will only buy a quart of wheat or 3 quarts of barley (Revelation 6:5-6).
- Seal 4: One quarter of the world's population die from violence, famine, pestilence, and animal attacks (Revelation 6:7-8).
- Seal 5: People who believed in Jesus after the Rapture may begin to be killed for their faith, just like many martyrs were in the past (Revelation 6:9-11), thus leading to a great number of people standing before God in heaven (Revelation 7:9-17, Matthew 24:9-10).
- Seal 6: Something causes an earthquake that moves every mountain and island from their places, and meteorites strike many cities (Revelation 6:12-17).
- Seal 7: Thunder, lightning, and an earthquake occur as the Trumpet judgments are prepared (Revelation 8:1-5).
The 7 Trumpets
- Trumpet 1: A third of the trees and all green grass is burned up (Revelation 8:7).
- Trumpet 2: Something like a large, burning mountain impacts the ocean, turning a third of it to blood, killing a third of the sea life, and destroying a third of the ships (Revelation 8:8-9).
- Trumpet 3: A star from heaven falls that contaminates a third of the freshwater streams and rivers and people die from the bitter water (Revelation 8:10-11).
- Trumpet 4: All sunlight, moonlight, and starlight reaching the earth is reduced by a third (Revelation 8:12).
- Trumpet 5: Demonic locusts are released on the world that sting and torment people for five months (Revelation 9:1-11).
- Trumpet 6: A third of humanity is killed by fire, smoke, and sulfur, perhaps centered around the Euphrates river (Revelation 9:18, 9:14).
- Trumpet 7: An earthquake, lightning, and hail, as the seven bowl judgments are prepared (Revelation 11:15-19).
The 7 Bowls
- Bowl 1: Painful sores break out on people who took the Mark of the Beast and worshiped the Antichrist (Revelation 16:2).
- Bowl 2: The sea somehow becomes like the "blood of a corpse" and everything living in it dies (Revelation 16:3).
- Bowl 3: The freshwater rivers also become like blood (Revelation 16:4-7).
- Bowl 4: The sun scorches people with intense heat, causing them to cry out in pain (Revelation 16:8-9).
- Bowl 5: The Antichrist's kingdom is plunged into darkness and people moan from their sores (Revelation 16:10-11).
- Bowl 6: The Euphrates river dries up to allow the kings from the east to bring their armies for the battle of Armageddon (Revelation 16:12-16).
- Bowl 7: The strongest earthquake in history occurs, many cities are destroyed, and extremely heavy hail falls (Revelation 16:17-21).
This might all sound unbelievable now, but similar judgments happened back before the Exodus of Israelites from Egypt, to convince Pharaoh to let the Israelites leave (Exodus 7:4-5). You can read about these judgments in the Biblical book of Exodus, chapters 7 to 12.
God has the power to do whatever he wants, and so I think even if we don't understand every detail of these judgments now, they will all be fulfilled perfectly. If you are alive on Earth during the Tribulation, you should be able to compare what you see in the book of Revelation to current events that are happening, as irrefutable proof that what the world is experiencing is divine judgment.
Additionally, during the Tribulation, two prophets will appear in Jerusalem and will prophesy for 1,260 days (Revelation 11:3):
They have the power to shut the sky, that no rain may fall during the days of their prophesying, and they have power over the waters to turn them into blood and to strike the earth with every kind of plague, as often as they desire (Revelation 11:6).
So that will also be going on along with all the rest of these judgments.
Finally, the battle of Armageddon happens, when the Antichrist will bring his armies down toward Jerusalem and try to make a final stand against Jesus who returns in the clouds with the armies of heaven (Revelation 19:11-19). But Jesus will win, the Antichrist's armies will be destroyed, and the Antichrist and False Prophet will be thrown into the lake of fire (Revelation 19:20-21).
When we consider all of these divine judgments that are prophesied to occur, it makes sense why Jesus says the Tribulation will be the worst time in humanity's history, and that if the Tribulation wasn't shortened, everyone would die (Matthew 24:21-22).
It's Not Too Late For You
Now, if you are reading this after millions or maybe even billions of people have suddenly disappeared, then you have missed the Rapture.
And due to all the divine judgments that will be happening over the next few years on Earth, there is a high chance you will end up dying in one way or another (Amos 5:18-19). So now is a really good time to make sure you know what your eternal destiny will be.
It's important for you to know that every human being is a sinner (Romans 3:10, 3:23), even those of us who were raptured.
Being a sinner means that we all act or have acted in ways that are not perfectly good or loving. Sinning is a violation of God's instructions for how all people should behave, which is summed up as loving God and loving others (Luke 10:27). And committing even one sin means we deserve eternal death:
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord (Romans 6:23).
But even now, it's not too late for you to choose to believe in Jesus as your personal savior, who died on the cross for your sins. He experienced the suffering and death that you justly deserve, to satisfy God's justice and pay the divine penalty for your sins, so that you can have eternal life for free.
It's extremely easy to accept this free offer of eternal life:
If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved (Romans 10:9).
So if you have believed in Jesus, now, even if you die, you can be assured that someday you will be resurrected and will receive an immortal body that will never age, get sick, or be able to be injured or destroyed. You'll be reunited with everyone who disappeared in the Rapture, and with all the people who believed in God throughout history.
You'll get to live forever with God the Father, Jesus, the Holy Spirit, angels, and all the saints in the New Heaven and New Earth, where there will be no more crying, suffering, or death (Revelation 21, Hebrews 12:22-24).
There is far more that could be said about all of this, but for now, that's enough. I truly hope you have taken this advice to believe in Jesus.
Whether you have believed in Jesus or not, please continue reading, because there is a very important warning you need to hear.
A Warning About The Antichrist, False Prophet, and Mark of the Beast
After the Rapture, the next major thing to watch for is the appearance of the Antichrist.
He will likely appear to be a good guy with incredible charisma and intelligence. He will rapidly rise up in power and influence over the world, initially, through peaceful means (Revelation 6:1-2).
Ten world leaders will hand over their authority to him (Daniel 7:24, Revelation 17:12-13). He will confirm some sort of covenant between "many" that is designed to last for seven years (Daniel 9:27).
But don't trust him or be fooled by him, because he's actually working for Satan (Revelation 13:4-9, Matthew 24:4-5, Matthew 24:23-27).
Most people will follow him and be deceived by his lies:
When the wicked one appears, Satan will pretend to work all kinds of miracles, wonders, and signs. Lost people will be fooled by his evil deeds. They could be saved, but they will refuse to love the truth and accept it. So God will make sure they are fooled into believing a lie. All of them will be punished, because they would rather do evil than believe the truth (2 Thessalonians 2:9-12, CEV).
Halfway through the Tribulation, the Antichrist will declare himself to be God in the rebuilt Jewish temple on the Temple Mount, in Jerusalem (Daniel 9:27, Matthew 24:15-20, Mark 13:14-18):
He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God (2 Thessalonians 2:4, NIV).
As a result, the Antichrist will start persecuting anyone who believes in Jesus or who refuses to worship the Antichrist as God (Revelation 13:7-8, Daniel 7:25).
There will also be a powerful religious leader (the False Prophet) who will endorse the Antichrist and do miracles for him, which will be extremely impressive and deceive even more people:
It [the False Prophet] performs great signs, even making fire come down from heaven to earth in the sight of all; and by the signs that it is allowed to perform on behalf of the beast, it deceives the inhabitants of earth, telling them to make an image for the beast that had been wounded by the sword and yet lived; and it was allowed to give breath to the image of the beast, so that the image of the beast could even speak and cause those who would not worship the image of the beast to be killed (Revelation 13:13-15, NRSVA).
Even more importantly, the False Prophet will require everyone to take the Mark of the Beast or be cut off from all ability to buy and sell:
Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell who does not have the mark, that is, the name of the beast or the number of its name. This calls for wisdom: let anyone with understanding calculate the number of the beast, for it is the number of a person. Its number is six hundred and sixty-six.(Revelation 13:16-18, NRSVA).
So this warning is VERY, VERY IMPORTANT to pay attention to:
If, for any reason, someone says that you can't buy or sell without opting into some system that requires a mark in/on your right hand or forehead, and/or someone tells you to worship someone who isn't Jesus returning in the clouds wearing a robe dipped in blood, sitting on a white horse, surrounded by the armies of heaven (Revelation 19:11-14), in a display that will be like lightning flashing from the east to the west (Matthew 24:27, Luke 17:24), DON'T DO IT. Even if it costs you your life.
That's because:
Those who worship the beast and its image, and receive a mark on their foreheads or on their hands, they will also drink the wine of God’s wrath, poured unmixed into the cup of his anger, and they will be tormented with fire and sulphur in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment goes up for ever and ever. There is no rest day or night for those who worship the beast and its image and for anyone who receives the mark of its name (Revelation 14:9-11).
So please, just don't accept the Mark!
I'm convinced that if you have truly believed in Jesus, the Holy Spirit will give you the ability to say no to taking the Mark, no matter what suffering you might have to face, even including torture or death.
You won't be able to take the Mark of the Beast because your eternal salvation is guaranteed the moment you believed in Jesus. You can never lose it or do anything to renounce it, due to how the Holy Spirit lives inside you now:
In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory (Ephesians 1:13-14).
There are some end-times Bible teachers who argue that this divine sealing was only for Christians who lived before the Rapture. These teachers argue that people who believe in Jesus during the Tribulation (a.k.a. Tribulation saints) will have to keep themselves saved by their own effort.
But this can't be true, because eternal salvation is always by God's grace alone, through faith in Christ alone, and has nothing to do with our actions/works, or else people could brag that they did something to earn their salvation:
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast (Ephesians 2:8-9).
This verse would still apply to the Tribulation saints, and not just to Christians who believed in Jesus before the Rapture. There will not be some people who receive eternal life only by faith in God, and others who have to do something to earn it. As Charles Ryrie explains:
The basis of salvation in every age is the death of Christ; the requirement for salvation in every age is faith; the object of faith in every age is God; the content of faith changes in the various dispensations.1
So in all human history, everyone who has ever been saved had faith in God, and was saved only because Jesus died for them. Yet the specific details of what these saved people knew about God and about God's promise to send Jesus to die for their sins varied, since other than believing in God and/or Jesus, no specific theological knowledge is necessary for salvation.
How faithful people lived out their faith also varied, depending on what God called them to do. Some examples of difficult things that God called his faithful people to do can be seen in the Bible, the book of Hebrews, chapter 11.
So for believers in Jesus during the Tribulation, your faith will be demonstrated by standing strong and refusing to take the Mark of the Beast. Because if it were possible for you to be both sealed with the Holy Spirit and take the Mark of the Beast, there would be a conflict with regard to your eternal destiny. God won't let that happen.
Therefore, you can be confident that God will give you the ability to stand strong and perhaps even face death as a testimony of your faith in him. But don't worry: if you are killed for your faith, you'll be resurrected and rewarded by ruling with Jesus when he returns at his Second Coming (Revelation 20:4).
What You Should Do Now If The Rapture Has Happened
If the Rapture has happened, then here's what I would strongly recommend you should do as soon as you can:
- If you didn't do it earlier, please believe that Jesus died for your sins so that you can have eternal life. Then no matter what happens, your eternal future in heaven is guaranteed (Ephesians 1:13-14).
- Pray to God and ask him to give you strength and to protect you and provide for you, and to give you courage to stand strong in your faith during the persecution that will be coming. Also pray for discernment to not be deceived by lies and deception, and to have wisdom to know what to do.
- Find or buy a Bible, because I suspect they will quickly be banned, confiscated, and destroyed. I also suspect the authorities will ban and destroy other Christian books and take down Christian websites. The homes of people who were raptured should have at least one Bible, and most churches store Bibles in their pews, offices, or libraries. Keep some extra Bibles around to give to others who have also chosen to believe in Jesus who don't already have one.
- Start reading the Bible for yourself, and pray that the Holy Spirit will help you understand it. I would recommend for you to begin with the book of John, then read Matthew or Luke. The book of Revelation, especially chapters 6 to 19, will give you an outline of what to expect in the future, although some of it is presented symbolically. The book of Psalms may also be comforting and reassuring to you. If you're lucky, the homes of people who were raptured might also contain other Bible study resources and books on theology that could be helpful for you. But don't just believe everything in these other books without verifying it with the Bible (Acts 17:11).
- Tell your family, friends, coworkers, and neighbors that the Rapture has just happened, and warn them to not believe whatever lies are being told by the authorities and experts. Warn them about what will be happening during the Tribulation, and tell them that they also need to believe in Jesus, and to not take the Mark of the Beast.
- Begin stockpiling food, medicine, and basic supplies to help get you through the third Seal judgement and survive without taking the Mark of the Beast. Share generously with others in need (Matthew 25:34-40), and trust that God will help you have enough (Matthew 6:25-33).
- Pray that God will give you wisdom about where you should go and what you should do in case you need to leave your current location due to disasters or violence.
- Find a group of other new Christians to meet with to support and encourage each other, to pray for each other, to study the Bible, and to worship God together. Be careful, though, because there will be many churches still operating after the Rapture because they were run and attended by people who weren't truly Christians. Many of these churches might be promoting a new worldwide false religion that will persecute real Christians who will refuse to go along with it (Revelation 17). If the church you find to attend isn't talking about how you need to believe in Jesus to have eternal life, which is fully a gift of God's grace, and isn't warning you about the Tribulation, or about not taking the Mark of the Beast, or about not worshiping the Antichrist, I would go elsewhere.
What You Should Do Now if the Rapture Has Not Yet Happened
If the Rapture has not yet happened, then here's my list of what I think you should do now while you still can:
- If you haven't done so before, believe that Jesus died for your sins so that you can have eternal life. Then look forward to one day being with Jesus, whether at the Rapture or perhaps sooner.
- In the meantime, try to find a faithful church to attend which preaches that we are saved only by putting our faith in Christ, and not by anything we can do. (If you can't find a good church, I'd recommend watching pastor JD Farag's online services at jdfarag.org while you keep looking for a home church). Read your Bible and make time each day to pray to God/Jesus/the Holy Spirit to get to know him better, and to be strengthened and comforted in difficult times.
- If you know people who might be left behind, talk to them now about Jesus, and about the Rapture and the Tribulation. Offer to give them a Bible, if you have a spare one, or buy them one as a gift. Warn them about what will happen, and encourage them to put their faith in Jesus so they don't miss the Rapture. Pray that God will soften their hearts and open their ears and eyes to the truth. Or, in the worst case, pray that after the Rapture, they will wake up and realize you were telling them the truth, and that they will believe in Jesus then.
- Do good things for God while you still can, to make a difference in the world and earn heavenly rewards (1 Corinthians 3:12-15, Matthew 25:14-30, John 9:4, Luke 19:13).
Finally, I would encourage you to write a letter like the one I've written in this blog post to your currently non-Christian family, friends, or anyone else who might find it once the Rapture happens. Put a copy of your letter with your will or other important documents, and also put a copy in an obvious place where it will be seen by someone who enters your home to look for you (or for supplies) after you are raptured.
In your letter, do like I did earlier in this post: explain why you have suddenly disappeared, where you are now, and what will be happening next, and for people to avoid the Mark of the Beast at all costs. Encourage your reader to put their faith in Jesus, and give them any last wishes you might want to tell them.
Feel free to copy parts of this blog post and make use of it in your own letter, or simply copy my whole blog post into a text editor and print it to keep with your letter as a helpful resource for anyone who is left behind. If you want to include even more information about the end times, you can make use of my other relevant blog posts:

- Important: Regarding Buying and Selling
- Climate Change and the End Times
- The Rapture Is Coming: Watch For The Seven-Year Covenant With 'Many'
- Christians Should Not Fear Death

If you have unbelieving family members, friends, or roommates, you could also explain to them now why you are writing this letter and where you are putting it, so that when the Rapture happens, they can find it for themselves if they don't want to read it now.
(Of course, if they do want to read it now, then that's a fantastic opportunity to share your faith with them, and to encourage them to believe in Jesus so that they can be raptured too!)
Personally, I also have a few books on my bookshelf that I've clustered together in plain sight and wrapped with a piece of white paper, on which I wrote in large text: "PLEASE READ these books in case of SUDDEN DISAPPEARANCE of MILLIONS of PEOPLE". I hope that if my landlord, emergency services, or a looter comes into my apartment after the Rapture, they'll see the note and be intrigued enough to take the books. For me, these books include:
- a Bible.
- Charles C. Bing, Simply By Grace: An Introduction to God's Life Changing Gift (Grand Rapids, MI: Kregel Publications, 2009). This is my favorite short and clear book about the gospel and the Christian life.
- John F. Walvoord, Revelation, The John Walvoord Prophecy Commentaries (Chicago, IL: Moody Publishers, 2011). I recommend this book as a clear and easy to understand commentary on the book of Revelation. Another good option is Tim Lahaye, Revelation Unveiled (Grand Rapids, MI: Zondervan, 1999).
- Mark Hitchcock, Who Is The Antichrist? (Eugene, OR: Harvest House Publishers, 2011). This book should help those left behind identify the Antichrist and not fall for his deception.
- Gary Bates, Alien Intrusion: UFOs and the Evolution Connection, Updated and Expanded (Powder Springs, GA: Creation Book Publishers, 2011). This book offers a persuasive Christian explanation for what 'aliens' actually are (i.e., demons). I included it because I think the Rapture will most likely be explained away as a mass alien abduction, and I don't want people to fall for that lie.
So you could also go through your books and see if there are any useful ones you can point people to after the Rapture. Or, maybe consider buying some of the above if you want some good resources to leave behind for others.
Conclusion
Based on everything that's happening in the world now, I think we can see things being set up for the first few seal judgments and other signs of the end times. The seven-year covenant with 'many' may also be on the verge of being confirmed.
So I would encourage you to write your letter and talk to your non-Christian family and friends about Jesus and the Rapture very soon, because Jesus could come take Christians to heaven at any moment.
Now when these things begin to take place, straighten up and raise your heads, because your redemption is drawing near (Luke 21:28).
