4. Therefore I have in this letter, which has reached you, shown by passages of Holy Scripture, which you can examine for yourselves, that our good works and pious prayers and right faith could not possibly have been in us unless we had received them all from Him, concerning whom the Apostle James says, “Every good gift and every perfect gift is from above, and cometh down from the Father of lights.” And so no man can say that it is by the merit of his own works, or by the merit of his own prayers, or by the merit of his own faith, that God’s grace has been conferred upon him; nor suppose that the doctrine is true which those heretics hold, that the grace of God is given us in proportion to our own merit. This is altogether a most erroneous opinion; not, indeed, because there is no desert, good in pious persons, or evil in impious ones (for how else shall God judge the world?), but because a man is converted by that mercy and grace of God, of which the Psalmist says, “As for my God, His mercy shall prevent me;” so that the unrighteous man is justified, that is, becomes just instead of impious, and begins to possess that good desert which God will crown when the world shall be judged.
