Brothers and sisters, we want you to know what happens to those who die. We don't want you to be sad, as other people are. They don't have any hope.
References for 1 Thessalonians 4:13
We believe that Jesus died and rose again. When he returns, many who believe in him will have died already. We believe that God will bring them back with Jesus.
That agrees with what the Lord has said. When the Lord comes, many of us will still be alive. We tell you that we will certainly not go up before those who have died.
The Lord himself will come down from heaven. We will hear a loud command. We will hear the voice of the leader of the angels. We will hear a blast from God's trumpet. Many who believe in Christ will have died already. They will rise first.
After that, we who are still alive and are left will be caught up together with them. We will be taken up in the clouds. We will meet the Lord in the air. And we will be with him forever.
So cheer each other up with these words of comfort.
