1 Thessalonians 4:14-17
For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
This section of Scripture gives us details about our resurrection. Paul wrote that Jesus will return, with those believers who have already died. He will descend from heaven with a shout, voice of the archangel, and with the trump of God. The bodies of dead believers will be raised and then we, which are alive, will be raised to meet Jesus in the air. This is our hope, culmination of our salvation, and the beginning of spending eternity with the One who has saved us.
