Here is the passage in 1 Thessalonians 4 that most people use as proof of the pre-trib rapture. Hope this helps...
13Brothers, we do not want you to be ignorant about those who fall asleep, or to grieve like the rest of men, who have no hope. 14We believe that
Jesus died and rose again and so we believe that God will bring with Jesus those who have fallen asleep in him. 15According to the Lord's own word,
we tell you that we who are still alive, who are left till the coming of the Lord, will certainly not precede those who have fallen asleep. 16For the
Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ
will rise first. 17After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And
so we will be with the Lord forever. 18Therefore encourage each other with these words.
