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. 4 Then each of you will control his own body and live in holiness and honor- 5 not in lustful passion like the pagans who do not know God and his ways. 6 Never harm or cheat a fellow believer in this matter by violating his wife, for the Lord avenges all such sins, as we have solemnly warned you before. 7 God has called us to live holy lives, not impure lives. 8 Therefore, anyone who refuses to live by these rules is not disobeying human teaching but is rejecting God, who gives his Holy Spirit to you.
9 But we don't need to write to you about the importance of loving each other, for God himself has taught you 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.

(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.
