41 Furthermore then we beseech [1] you, brethren, and exhort you by the Lord Jesus, that as ye have received of us how ye ought to walk and to please God, so ye would abound more and more. 2 For ye know what commandments we gave you by the Lord Jesus. 3 For this is the will of God, even your sanctification, that ye should abstain from fornication:
41 As for other matters, brothers and sisters, we instructed you how to live in order to please God, as in fact you are living. Now we ask you and urge you in the Lord Jesus to do this more and more. 2 For you know what instructions we gave you by the authority of the Lord Jesus. 3 It is God's will that you should be sanctified: that you should avoid sexual immorality;
41 Finally, then, brothers,
41 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. 2 You know the guidelines we laid out for you from the Master Jesus. 3 God wants you to live a pure life. Keep yourselves from sexual promiscuity.
41 Finally then, brethren, we urge and exhort in the Lord Jesus that you should abound more and more, just as you received from us how you ought to walk and to please God; 2 for you know what commandments we gave you through the Lord Jesus. 3 For this is the will of God, your sanctification: that you should abstain from sexual immorality;
41 Finally, dear brothers and sisters, we urge you in the name of the Lord Jesus to live in a way that pleases God, as we have taught you. You live this way already, and we encourage you to do so even more. 2 For you remember what we taught you by the authority of the Lord Jesus. 3 God's will is for you to be holy, so stay away from all sexual sin.
Matthew Henry's Commentary on 1 Thessalonians 4:1-3
Commentary on 1 Thessalonians 4:1-8
(Read 1 Thessalonians 4:1-8)
To abide in the faith of the gospel is not enough, we must abound in the work of faith. The rule according to which all ought to walk and act, is the commandments given by the Lord Jesus Christ. Sanctification, in the renewal of their souls under the influences of the Holy Spirit, and attention to appointed duties, constituted the will of God respecting them. In aspiring after this renewal of the soul unto holiness, strict restraint must be put upon the appetites and senses of the body, and on the thoughts and inclinations of the will, which lead to wrong uses of them. The Lord calls none into his family to live unholy lives, but that they may be taught and enabled to walk before him in holiness. Some make light of the precepts of holiness, because they hear them from men; but they are God's commands, and to break them is to despise God.
