1 Thessalonians 4:13-17

13But I would not have you to be ignorant, brethren, concerning them who are asleep, that ye sorrow not, even as others who have no hope. 14For if we believe that Jesus died and rose again, even so them also who sleep in Jesus will God bring with him. 15For this we say to you by the word of the Lord, that we who are alive and remain to the coming of the Lord shall not precede them who are asleep.1 16For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trumpet of God: and the dead in Christ shall rise first: 17Then we who 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.
