1 Thessalonians 4:1-18

Finally, brothers, we urge you and appeal to you in the Lord Jesus to make more and more progress in the kind of life that you are meant to live: the life that God wants, as you learnt from us, and as you are already living it. You have not forgotten the instructions we gave you on the authority of the Lord Jesus.
What God wants is for you all to be holy. He wants you to keep away from fornication, and each one of you to know how to use the body that belongs to him in a way that is holy and honourable, not giving way to selfish lust like the pagans who do not know God. He wants nobody at all ever to sin by taking advantage of a brother in these matters; the Lord always punishes sins of that sort, as we told you before and assured you. We have been called by God to be holy, not to be immoral; in other words, anyone who objects is not objecting to a human authority, but to God, who gives you his Holy Spirit.
As for loving our brothers, there is no need for anyone to write to you about that, since you have learnt from God yourselves to love one another, and in fact this is what you are doing with all the brothers throughout the whole of Macedonia. However, we do urge you, brothers, to go on making even greater progress and to make a point of living quietly, attending to your own business and earning your living, just as we told you to, so that you are seen to be respectable by those outside the Church, though you do not have to depend on them.
We want you to be quite certain, brothers, about those who have died, to make sure that you do not grieve about them, like the other people who have no hope. We believe that Jesus died and rose again, and that it will be the same for those who have died in Jesus: God will bring them with him. We can tell you this from the Lord’s own teaching, that any of us who are left alive until the Lord’s coming will not have any advantage over those who have died. At the trumpet of God, the voice of the archangel will call out the command and the Lord himself will come down from heaven; those who have died in Christ will be the first to rise, and then those of us who are still alive will be taken up in the clouds, together with them; to meet the Lord in the air. So we shall stay with the Lord for ever. With such thoughts as these you should comfort one another.
