On Rebuke and Grace

Let men then suffer themselves to be rebuked when they sin, and not conclude against grace from the rebuke itself, nor from grace against rebuke; because both the righteous penalty of sin is due, and righteous rebuke belongs to it, if it is medicinally applied, even although the salvation of the ailing man is uncertain; so that if he who is rebuked belongs to the number of the predestinated, rebuke may be to him a wholesome medicine; and if he does not belong to that number, rebuke may be to him a penal infliction.

Under that very uncertainty, therefore, it must of love be applied, although its result is unknown; and prayer must be made on his behalf to whom it is applied, that he may be healed. But when men either come or return into the way of righteousness by means of rebuke, who is it that works salvation in their hearts but that God who gives the increase, whoever plants and waters, and whoever labours on the fields or shrubs—that God whom no man's will resists when He wills to give salvation? For so to will or not to will is in the power of Him who wills or wills not, as not to hinder the divine will nor overcome the divine power. For even concerning those who do what He wills not, He Himself does what He will.
