1 Thessalonians 4:12-16

so that you will behave properly toward outsiders and not be in any need. Those Who Died in Christ

But we do not want you to be uninformed, brothers and sisters, about those who are asleep, so that you will not grieve as indeed the rest of mankind do, who have no hope.

For if we believe that Jesus died and rose from the dead, so also God will bring with Him those who have fallen asleep through Jesus.

For we say this to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will not precede those who have fallen asleep.

For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.
