12:3-8 Pride is a sin in us by nature; we need to be cautioned and armed against it. All the saints make up one body in Christ, who is the Head of the body, and the common Centre of their unity. In the spiritual body, some are fitted for and called to one sort of work; others for another sort of work. We are to do all the good we can, one to another, and for the common benefit. If we duly thought about the powers we have, and how far we fail properly to improve them, it would humble us. But as we must not be proud of our talents, so we must take heed lest, under a pretence of humility and self-denial, we are slothful in laying out ourselves for the good of others. We must not say, I am nothing, therefore I will sit still, and do nothing; but, I am nothing in myself, and therefore I will lay out myself to the utmost, in the strength of the grace of Christ. Whatever our gifts or situations may be, let us try to employ ourselves humbly, diligently, cheerfully, and in simplicity; not seeking our own credit or profit, but the good of many, for this world and that which is to come.

to every man that is among you, not to think, &c.—It is impossible to convey in good English the emphatic play, so to speak, which each word here has upon another: "not to be high-minded above what he ought to be minded, but so to be minded as to be sober-minded" [Calvin, Alford]. This is merely a strong way of characterizing all undue self-elevation.

according as God hath dealt to every man the measure of faith—Faith is here viewed as the inlet to all the other graces, and so, as the receptive faculty of the renewed soul—that is, "as God hath given to each his particular capacity to take in the gifts and graces which He designs for the general good."
