Psalms 145:6

73. Moreover, great hope has been given, and is given, by Him who does not deceive when He promises: for He says, “Every one that asketh, receiveth; and he that seeketh, findeth; and to him that knocketh, it shall be opened.” Hence there is need of perseverance, in order that we may receive what we ask, and find what we seek, and that what we knock at may be opened. Now, just as He talked of the fowls of heaven and of the lilies of the field, that we might not despair of food and clothing being provided for us, so that our hopes might rise from lesser things to greater; so also in this passage, “Or what man is there of you,” says He, “whom if his son ask bread, will he give him a stone? Or if he ask a fish, will he give him a serpent? If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that as …

What then must we do, if we are not to hope in sons of men, nor in princes? What must we do? “Blessed is he whose Helper is the God of Jacob” ( ver. 5 ): not this man or that man; not this angel or that angel; but, “blessed is he whose Helper is the God of Jacob:” for to Jacob also so great an Helper was He, that of Jacob He made him Israel. O mighty help! now he is Israel, “seeing God.” While then thou art placed here, and a wanderer not yet seeing God, if thou hast the God of Jacob for thy Helper, from Jacob thou wilt become Israel, and wilt be “seeing God,” and all toil and all groans shall come to an end, gnawing cares shall cease, happy praises shall succeed. “Blessed is he whose Helper is the God of Jacob;” of this Jacob. …

Our God Himself, Whom we glorify as Three in One, created the heaven and the earth and all that they contain , and brought all things out of nothing into being: some He made out of no pre-existing basis of matter, such as heaven, earth, air, fire, water: and the rest out of these elements that He had created, such as living creatures, plants, seeds. For these are made up of earth, and water, and air, and fire, at the bidding of the Creator.

This adversary’s wiles then let us beware of, not only in the enticements of the palate, but also in our purpose of abstinence. For he who knew how to bring death upon mankind by means of food, knows also how to harm us through our very fasting, and using the Manichæans as his tools, as he once drove men to take what was forbidden, so in the opposite direction he prompts them to avoid what is allowed. It is indeed a helpful observance, which accustoms one to scanty diet, and checks the appetite for dainties: but woe to the dogmatizing of those whose very fasting is turned to sin. For they condemn the creature’s nature to the Creator’s injury, and maintain that they are defiled by eating those things of which they contend the devil, not God , is the author: although absolutely nothing that exists is evil, nor is anything in nature included in the actually bad. …
