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.

9. brotherly love, &c.—referring here to acts of brotherly kindness in relieving distressed brethren. Some oldest manuscripts support English Version reading, "YE have"; others, and those the weightiest, read, "WE have." We need not write, as ye yourselves are taught, and that by God: namely, in the heart by the Holy Spirit (Joh 6:45; Heb 8:11; 1Jo 2:20, 27).

to love—Greek, "with a view to," or "to the end of your loving one another." Divine teachings have their confluence in love [Bengel].
