Noah and his family escaped from God's Judgment. Before going to the Great Tribulation, God will rescue His people. We call it rapture of the church.

Then two men will be in the field: one will be taken and the other left. Two women will be grinding at the mill: one will be taken and the other left. Watch therefore, for you do not know what hour your Lord is coming. (Matthew 24:40-42)

Two men will be in the field. One is taken and the other left behind. If Jesus is coming for the rapture at the end of the world, there is no Christian men raptured because all the true Christians were martyred already at that time because they refused the mark of the beast. In the end of the world, there will be the last war and there will be nuclear attack all around the world. And people can not peacefully in the field.

“Behold, I am coming as a thief. Blessed is he who watches, and keeps his garments, lest he walk naked and they see his shame.” (Rev 16:15)

If Jesus is coming for the rapture of the church in the end of the world, there is no reason Jesus said he is coming like a thief at night. Once the Antichrist appears, the world will be end in 7 years. So post-tribulation rapture is not biblical.

Jesus is coming like a thief at night. That's why we have to be ready all the time. We don't know when he is coming.

We are waiting for Jesus coming for the rapture of the church. Still many people are debating pre-tribulation rapture or mid-tribulation or post-tribulation rapture.

Jesus is coming for the rapture before the tribulation. Jesus said in Matthew 24:37 that the Son of man comes as the days of Noah.
