4:10-19 It is a good work to succour and help a good minister in trouble. The nature of true Christian sympathy, is not only to feel concern for our friends in their troubles, but to do what we can to help them. The apostle was often in bonds, imprisonments, and necessities; but in all, he learned to be content, to bring his mind to his condition, and make the best of it. Pride, unbelief, vain hankering after something we have not got, and fickle disrelish of present things, make men discontented even under favourable circumstances. Let us pray for patient submission and hope when we are abased; for humility and a heavenly mind when exalted. It is a special grace to have an equal temper of mind always. And in a low state not to lose our comfort in God, nor distrust his providence, nor take any wrong course for our own supply. In a prosperous condition not to be proud, or secure, or worldly. This is a harder lesson than the other; for the temptations of fulness and prosperity are more than those of affliction and want. The apostle had no design to urge them to give more, but to encourage such kindness as will meet a glorious reward hereafter. Through Christ we have grace to do what is good, and through him we must expect the reward; and as we have all things by him, let us do all things for him, and to his glory.

13. I can do all things—Greek, "I have strength for all things"; not merely "how to be abased and how to abound." After special instances he declares his universal power—how triumphantly, yet how humbly! [Meyer].

through Christ which strengtheneth me—The oldest manuscripts omit "Christ"; then translate, "In Him who giveth me power," that is, by virtue of my living union and identification with Him, who is my strength (Ga 2:20). Compare 1Ti 1:12, whence probably, "Christ" was inserted here by transcribers.
