31.
When, therefore, it is said, "The Lord your God tempteth (proveth) you, that He may know if ye love Him," 1 the words "that He may know" are employed for what is the real state of the case, that He may make you know: just as we speak of a joyful day, because it makes us joyful; of a sluggish frost, because it makes us sluggish; and of innumerable things of the same sort, which are found either in ordinary speech, or in the discourse of learned men, or in the Holy Scriptures. And the heretics who are opposed to the Old Testament, not understanding this, think that the brand of ignorance, as it were, is to be placed upon Him of whom it is said, "The Lord your God tempteth you:" as if in the Gospel it were not written of the Lord, "And this He said to tempt (prove) him, for He Himself knew what He would do." 2 For if He knew the heart of him whom He was tempting, what is it that He wished to see by tempting him? But in reality, that was done in order that he who was tempted might become known to himself, and that he might condemn his own despair, on the multitudes being filled with the Lord's bread, while he had thought they had not enough to eat.
