John Calvin's Bible Commentary
Psalms 37:25
25I have been young, I am also become old. The meaning of these words is not in the least doubtful, namely, that David, even when he was become an old man, had not seen any of the righteous, or any of their children, begging their bread. But here there arises a question of some difficulty with respect to the fact stated; for it is certain that many righteous men have been reduced to beggary. And what David here declares as the result of his own experience pertains to all ages. Besides, he refers in this verse to the writings of Moses, for in Deuteronomy 15:4, begging is reckoned among the curses of God; and the law, in that place, expressly exempts from it those who fear and serve God. How then does the consistency of this appear, that none of the righteous ever begged his bread, since Christ placed Lazarus among the most abject of them? (Luke 16:20.) I answer, that we must bear in mind what I have before said upon this subject, that with respect to the temporal blessings which God confers upon his people, no certain or uniform rule can be established. There are various reasons why God does not manifest his favor equally to all the godly in this world. He chastises some, while he spares others: he heals the secret maladies of some, and passes by others, because they have no need of a like remedy: he exercises the patience of some, according as he has given them the spirit of fortitude; and, finally, he sets forth others by way of example. But in general, he humbles all of them by the tokens of his anger, that by secret warnings they may be brought to repentance. Besides, he leads them, by a variety of afflictions, to fix their thoughts in meditation upon the heavenly life; and yet it is not a vain or imaginary thing, that, as is set forth in the Law, God vouchsafes earthly blessings to his servants as proofs of his favor toward them. I confess, I say, that it is not in vain, or for nought, that an abundance of earthly blessings, sufficient for the supply of all their wants, is promised to the godly. This, however, is always to be understood with this limitation, that God will bestow these blessings only in so far as he shall consider it expedient: and, accordingly, it may happen that the blessing of God may be manifested in the life of men in general, and yet some of the godly be pinched with poverty, because it is for their good. But if it happen that any of the faithful are brought to beggary, they should lift up their minds on high, to that blessed state in which God will largely recompense them for all that is now wanting in the blessings of this transitory life. We must also bear this in mind, that if God sometimes involve the faithful in the same punishments by which he takes vengeance upon the ungodly — seeing them, for example, affected with the same diseases, — in doing so there is no inconsistency; for although they do not come the length of contemning God, nor are devoted to wickedness, nor even act according to their own inclination, nor yield themselves wholly to the influence of sin like the wicked, yet are they not free of all blame; and, therefore, it need not surprise us though they are sometimes subjected to temporal punishments. We are, however, certain of this, that God makes such provision for his own people, that, being contented with their lot, they are never in want; because, by living sparingly, they always have enough, as Paul says, Philippians 6:12,
“I am instructed both to abound and to suffer need.”
