A friend of mine sent me this and honestly if the post trib belief is to be true I believe this is evidence of it
The most obvious text is the Olivet Discourse. This passage right here. Speaking both to and about the Jews who will be alive when this time comes, Jesus said:
20 Pray that your flight may not be in winter or on the Sabbath. 21 For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be. 22 And unless those days were shortened, no flesh would be saved; but for the elect's sake those days will be shortened. 23 Then if anyone says to you... 'Look, He is in the desert!' do not go out; or 'Look, He is in the inner rooms!' do not believe it. 27 For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be. 28 For wherever the carcass is, there the eagles will be gathered together. 29 Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken. 30 Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. 31 And He will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other. (Matthew 24:20-23, 26-31)
Now was that so hard?
