1 Thessalonians 4:1-8, 13-14

One final word, friends. We ask you—urge is more like it—that you keep on doing what we told you to do to please God, not in a dogged religious plod, but in a living, spirited dance. You know the guidelines we laid out for you from the Master Jesus. God wants you to live a pure life. Keep yourselves from sexual promiscuity. Learn to appreciate and give dignity to your body, not abusing it, as is so common among those who know nothing of God. Don’t run roughshod over the concerns of your brothers and sisters. Their concerns are God’s concerns, and he will take care of them. We’ve warned you about this before. God hasn’t invited us into a disorderly, grungy life but into something holy and beautiful—as beautiful on the inside as the outside. If you disregard this advice, you’re not offending your neighbors; you’re rejecting God, who is making you a gift of his Holy Spirit.

And regarding the question, friends, that has come up about what happens to those already dead and buried, we don’t want you in the dark any longer. First off, you must not carry on over them like people who have nothing to look forward to, as if the grave were the last word. Since Jesus died and broke loose from the grave, God will most certainly bring back to life those who died in Jesus.
