1 Thessalonians 4

Father, your word informs me that there will be loss of loved ones in this lifetime, and that that loss will lead to times of grieving and times of tears, but, in faith, I do not grieve as one who has no hope. For I believe that Jesus died and rose again and that, through Jesus, you, Father, will raise with Christ all those of yours who have fallen asleep.

Those who have fallen asleep will precede those who are left at the coming of the Lord Jesus when he descends from heaven. He will descend at the time appointed by you, Father, with a cry of command, with the voice of an archangel and with the sound of your trumpet, Father.

The dead in Christ will rise first. Then those who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air and so shall we always be with the Lord.
