41 And last of all, the prayer which we make to you from our heart and in the name of the Lord Jesus, is this: that as we made clear to you what sort of behaviour is pleasing to God, as in fact you are doing now, so you will go on in these ways, but more and more. 2 Because you have in mind the orders we gave you through the Lord Jesus. 3 For the purpose of God for you is this: that you may be holy, and may keep yourselves from the desires of the flesh; 4 So that every one of you may keep his body holy and in honour; 5 Not in the passion of evil desires, like the Gentiles, who have no knowledge of God; 6 And that no man may make attempts to get the better of his brother in business: for the Lord is the judge in all these things, as we said to you before and gave witness. 7 Because it is God's purpose that our way of life may be not unclean but holy. 8 Whoever, then, goes against this word, goes against not man but God, who gives his Holy Spirit to you.
9 But about loving the brothers, there is no need for me to say anything to you in this letter: for you have the teaching of God that love for one another is right and necessary;

(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.

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.
