For this is the will of God: your sanctification, that you abstain from sexual immorality,

 4:13-18 We do not wish you to be ignorant, brothers, about those who are asleep, because we do not wish you to sorrow as the rest of people do because they have no hope. For if we believe that Jesus died and rose again, so also we can be sure that God will bring with him those who have fallen asleep through Jesus. For we tell you this, not by our own authority but by the word of the Lord, that we who are alive, who survive until the coming of the Lord, will certainly not take precedence over those who have fallen asleep. For the Lord himself will descend from heaven, with a shout of command, with the voice of an archangel and with the trumpet of God; and the dead who are in Christ will rise first, and then we who are alive, who survive, will be caught up by the clouds together with them to meet the Lord in the air. And so we shall be always with the Lord. So then encourage one another with these words.
