One verse that is very popular is found in 2 Cor. 5:8.
2Cor 5:8 We are confident, yes, well pleased rather to be absent from the body and to be present with the Lord.
They say Paul was teaching a doctrine that when we die we go right to heaven because he said to be absent from the body is to be present with the Lord.
Paul spoke much of when this would take place. He always looked to resuerrection, which is when he would get his new body and be done with the old one.
1Cor 15:53 For this corruptible must put on incorruption, and this mortal must put on immortality.
1Cor 15:54 So when this corruptible has put on incorruption, and this mortal has put on immortality, then shall be brought to pass the saying that is written: "Death is swallowed up in victory."
This is all taking place at the resurrection. Paul was looking forward to that day with joy. He understood how our new bodies would be free from suffering and pain of which Paul was very familuar with. This is why he said what he said when he said, "I would much rather be, absent for the body and present with the Lord." And when did Paul believe he would be free from his corrupt body and be with the Lord? At the resurrection...
1 Thess 4:15-17 15 For this we say to you by the word of the Lord, that we who are alive [and] remain until the coming of the Lord will by no means precede those who are 4 asleep. For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first.Then we who are alive [and] remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.
