Not really:
1 Thess 4:
13 Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest of mankind, who have no hope.
14For we 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 word, we tell you that
we who are still alive,
who are left until 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.
17 After 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 one another with these words.
Paul here talks as if the day was about to come and he knew for sure it was around the corner. He assured his listeners and he confidently counted himself among those that will be alive when the Lord comes.
And here:
2 Cor 4:
11For we who are alive are always being given over to death for Jesus’ sake, so that his life may also be revealed in our mortal body.
12So then, death is at work in us, but life is at work in you.
13It is written: “I believed; therefore I have spoken.”
b Since we have that same spirit of
c faith, we also believe and therefore speak,
14because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus and present us with you to himself.
15All this is for your benefit, so that the grace that is reaching more and more people may cause thanksgiving to overflow to the glory of God.
Here Paul counts himself amongst those that will die and be raised to be caught up together with his 1st century audience.
Can we say Paul was confused? No, he was indeed under the inspiration of the Holy spirit and he knew perfectly what he was talking about. Resurrection is not a distant future, one day event but a daily occurrence in the spiritual realm.
What were all of them waiting for? they were waiting for the Lord to come with those that had slept in the Lord, but what was the Lord waiting for? Peter's death is the one that marked the beginning of Church era as was promised by the Lord.
You can't understand these things unless you understand Daniel's timeline.
