1 Finally then, brothers, we request and urge you, in [the fellowship of] the Lord, that you should live [dedicated lives] and please God. Just as you people received direction from us [on doing this], see that you [continue to] do it more and more.
2 For you know [i.e., are aware of] the instructions we gave you by the authority of the Lord Jesus.
3 For it is God's will that you should be dedicated to Him, [that is], you should avoid sexual immorality.
4 Each of you should know how to control his own body in a dedicated and honorable way,
5 not in passionate lust, as the [unconverted] Gentiles, who do not know God, do.
6 And none of you should violate and exploit his brother [or sister] in such a matter. For the Lord will punish people for all these things, just as we told you before and warned you.
7 For God did not call us to be morally impure, but to be dedicated to Him.
8 So, the person who rejects [this exhortation] is not [merely] rejecting what man says but God [Himself], who gives His Holy Spirit to you.
9 Now you people do not need anyone to write to you about loving [your] brothers, for you yourselves have been taught by God to love one another.
10 For you certainly do practice it toward all the brothers [and sisters] throughout Macedonia. [Note: This was the province in which Thessalonica was located]. Yet we urge you, brothers, to continue doing it more and more.
11 [We also urge you to] make it your aim to live a quiet life, and to attend to your own business matters, and to work with your hands, as we urged you. [Note: Possibly this exhortation was directed toward the tendency of some people there to neglect ordinary responsibilities in view of an imminent return of Christ].
12 [Do these things] so that you will live in a proper way in front of outsiders [i.e., non-Christians], and not have [to depend on people for] any needs.
13 But we want you to be informed, brothers, concerning those who have fallen asleep [in death] so that you do not grieve, as other people do [i.e., the unsaved], who have no hope.
14 For if we believe that Jesus died and rose again [from the dead], [we also believe] that God will bring [back to life], along with Jesus, those in [fellowship with] Him who have fallen asleep [in death].
15 For we say this to you by [the authority of] the word of the Lord [Note: Paul was either quoting what Jesus had previously said, or was giving a revelation he had received from the Lord. See I Cor. 14:37], that we [Christians] who are [still] alive, who are left [on earth] when the Lord returns, will certainly not precede those who have fallen asleep. [Note: The point Paul is making is that the living will not be "changed" (I Cor. 15:51-52) and taken to heaven before the dead are raised].
16 For the Lord Himself [i.e., Jesus] will come down from heaven with a commanding shout [Note: This probably refers to Jesus' voice. See John 5:25, 28], [and] with the archangel's voice [i.e., Michael. See Jude 9] and with the sound of God's trumpet; [at this] the dead in [fellowship with] Christ will rise [from the dead] first.
17 Then, we who [will still] be alive, that are left, will be caught up together with them into the clouds to meet the Lord in the air. And so [from then on] we will always be with the Lord.
18 So, encourage one another with these words.
