Matthew 6:32

But, because that word is admissible in a carnal sense too, it cannot be so used without the religious remembrance withal of spiritual Discipline; for (the Lord) commands that bread be prayed for, which is the only food necessary for believers; for "all other things the nations seek after." The like lesson He both inculcates by examples, and repeatedly handles in parables, when He says, "Doth a father take away bread from his children, and hand it to dogs? " and again, "Doth a father give his son a stone when he asks for bread? " For He thus shows what it is that sons expect from their father.

(De Trin. xv. 13.) God did not gain this knowledge at any certain time, but before all time, without beginning of knowledge, foreknew that the things of the world would be, and among others, both what and when we should ask of Him. (De Civ. Dei, xii. 18.) As to what some say that these things are so many that they cannot be compassed by the knowledge of God; they ought with like reason to maintain further that God cannot know all numbers which are certainly infinite. But infinity of number is not beyond the compass of His understanding, who is Himself infinite. Therefore if whatever is compassed by knowledge, is bounded by the compass of him that has the knowledge, then is all infinity in a certain unspeakable way bounded by God, because it is not incomprehensible by His knowledge.

He doth not however stop at the rebuke, but having by this reproved and roused them, and shamed them with all strength of expression, by another argument He also comforts them, saying, "For your Heavenly Father knoweth that ye have need of all these things." He said not, "God knoweth," but, "your Father knoweth;" to lead them to a greater hope. For if He be a Father, and such a Father, He will not surely be able to overlook His children in extremity of evils; seeing that not even men, being fathers, bear to do so. And He adds along with this yet another argument. Of what kind then is it? That "ye have need" of them. What He saith is like this. What! are these things superfluous, that He should disregard them? Yet not even in superfluities did He show Himself wanting in regard, in the instance of the grass: but now are these things even necessary. So that what thou considerest a cause for thy being anxious, this I say is sufficient to draw thee from such anxiety. I mean, if thou sayest, "Therefore I must needs take thought, because they are necessary;" on the contrary, I say, "Nay, for this self-same reason take no thought, because they are necessary." Since were they superfluities, not even then ought we to despair, but to feel confident about the supply of them; but now that they are necessary, we must no longer be in doubt. For what kind of father is he, who can endure to fail in supplying to his children even necessaries? So that for this cause again God will most surely bestow them. For indeed He is the artificer of our nature, and He knows perfectly the wants thereof. So that neither canst thou say, "He is indeed our Father, and the things we seek are necessary, but He knows not that we stand in need of them." For He that knows our nature itself, and was the framer of it, and formed it such as it is; evidently He knows its need also better than thou, who art placed in want of them: it having been by His decree, that our nature is in such need. He will not therefore oppose Himself to what He hath willed, first subjecting it of necessity to so great want, and on the other hand again depriving it of what it wants, and of absolute necessaries. Let us not therefore be anxious, for we shall gain nothing by it, but tormenting ourselves. For whereas He gives both when we take thought, and when we do not, and more of the two, when we do not; what dost thou gain…
