41 For the rest, then, brethren, we beg you and exhort you in [the] Lord Jesus, even as ye have received from us how ye ought to walk and please God, even as ye also do walk, that ye would abound still more. 2 For ye know what charges we gave you through the Lord Jesus. 3 For this is [the] will of God, [even] your sanctification, that ye should abstain from fornication; 4 that each of you know how to possess his own vessel in sanctification and honour, 5 (not in passionate desire, even as the nations who know not God,) 6 not overstepping the rights of and wronging his brother in the matter, because the Lord [is] the avenger of all these things, even as we also told you before, and have fully testified. 7 For God has not called us to uncleanness, but in sanctification. 8 He therefore that [in this] disregards [his brother], disregards, not man, but God, who has given also his Holy Spirit to you.
9 Now concerning brotherly love ye have no need that we should write to you, for ye yourselves are taught of God to love one another.

(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.
Commentary on 1 Thessalonians 4:9-12
(Read 1 Thessalonians 4:9-12)
We should notice in others what is good, to their praise, that we may engage them to abound therein more and more. All who are savingly taught of God, are taught to love one another. The teaching of the Spirit exceeds the teachings of men; and men's teaching is vain and useless, unless God teach. Those remarkable for this or any other grace, need to increase therein, as well as to persevere to the end. It is very desirable to have a calm and quiet temper, and to be of a peaceable and quiet behaviour. Satan is busy to trouble us; and we have in our hearts what disposes us to be unquiet; therefore let us study to be quiet. Those who are busy-bodies, meddling in other men's matters, have little quiet in their own minds, and cause great disturbances among their neighbours. They seldom mind the other exhortation, to be diligent in their own calling, to work with their own hands. Christianity does not take us from the work and duty of our particular callings, but teaches us to be diligent therein. People often by slothfulness reduce themselves to great straits, and are liable to many wants; while such as are diligent in their own business, earn their own bread, and have great pleasure in so doing.
