Quite a few people teach the pre-tribulation rapture theory, citing so-called proofs from the Bible. But I beg to differ.
Jesus never talked of a pre-tribulation rapture. In fact He told us that Christians will be hated and persecuted, as we read in Matthew 10:22 and Matthew 24:9–13 respectively:
And you will be hated by everyone because of my name, but whoever will endure until the end, he will be saved. (Matthew 10:22)
And then they will deliver you to suffering, and they will kill you and you will be hated by all the nations because of my name. Then many will be subverted, and they will hate one another and will betray one another. And many false Prophets will arise and will deceive many. And because of the abundance of evil, the love of many will grow cold. But whoever will persevere until the end will have life. (Matthew 24:9–13)
There will be a final test for all Christians. There will be a battle of faith where Christians must publicly acknowledge Jesus as Lord or deny Him. This battle of faith will separate the sheep from the goats.
You, who will experience the time of the battle of faith, will be subject to great demands when you have to decide for or against Me…. For you will have to confess publicly, and that means that you either have to deny Me completely or stand up for Me with conviction. And you will be forced by brutal means to make a decision, which you will fear if your faith in Me is not strong enough so that you will only ever abide in Me with full trust, and I will not disappoint your faith. Precisely this battle of faith will still have to be waged before the end, because only then will the separation of the goats from the sheep take place, for then the flock of My Own will have emerged, whom My adversary will be unable to sway because they possess a living faith and are not mere Christians who only adhere to formalities, who will fail in the final battle…. (The Word of God, Proclamation 8727)
Only those Christians who persevere to the end will be saved. They will be raptured.
“But he that shall endure unto the end, the same shall be saved….” This is My promise, which certainly makes the greatest demand that you shall persevere until the end…. My promise will only come true with a small flock, for a great test of faith will be demanded of you, passing it will require much strength and an intimate bond with Me, since the believers will be harshly persecuted by the authorities and the human being can only offer resistance with My support by making use of My strength which will flow to him through his heartfelt contact with Me. He must belong to Me with all his will, with all his soul; and the strength of his faith in Me will give him the fortitude to resist. Then he would rather give up his life than Me, Whom he has recognised as the most loving Father from Whom he will never want to separate again…. And I will reward this strength of faith and love for Me, for he will become blissfully happy…. This small flock, which will remain loyal to Me even during the harshest battle of faith, will be rescued by Me from extreme adversity; I will move them to a place of peace in order to then give them the reshaped earth as their abode again, so that a new era will begin, a time of peace and of innermost unity with Me, so that I Myself will be able to stay amongst My Own because their deep love for Me allows for this…. The reward is truly magnificent but My Own will deserve it, for the last days on this earth will be incredibly difficult for them, and yet they will remain faithful to Me. They will abide until the end…. (The Word of God, Proclamation 8164)
The pre-tribulation rapture theory is a construct that will lead many astray. Do not believe those who teach that all Christians will be raptured before the Tribulation. These people are doing Christians a great disservice because Christians who buy into this pre-tribulation rapture theory will not be spiritually prepared. Only those who stand firm in their faith and remain loyal to Jesus until the end will be carried away.
