There were they in great fear, where no fear was: for God has scattered the bones of him that encamps against you: you have put them to shame, because God has despised them.
All Commentaries on Psalms 53:5 Go To Psalms 53
Augustine of Hippo
6. "Shall not all know that work iniquity, that devour My people for the food of bread"? (ver. 5). ...There is therefore here a people of God that is being devoured. Nay, "There is not one that doeth good, there is not so much as one." We reply by the rule above. But this people that is devoured, this people that suffereth evil men, this that groaneth and travaileth amid evil men, now out of sons of men have been made sons of God: therefore are they devoured. For, "The counsel of the needy man thou hast confounded, because the Lord is his hope." For ofttimes, in order that the people of God may be devoured, this very thing in it is despised, that it is the people of God. I will pillage, he saith, and despoil; if he is a Christian, what will he do to me? ...But what followeth? "I will convince thee, and will set thee before thy face." Thou wilt not now know so as thou shouldest be displeasing to thyself, thou shall know so as thou mayest mourn. For God cannot but show to the unrighteous their iniquity. If He is not to show, who will they be that are to say, "What hath profiled us pride, and what hath boasting of riches bestowed upon us?" For then shall they know, that now will not know. "Shall not all know?" etc. Why hath He added, "for the food of bread"? As it were as bread, they eat My people. For all other things which we eat, we can eat now these, now those; not always this vegetable, not always this flesh, not always these apples: but always bread. What is then, "Devour My people for the food of bread"? Without intermission, without cessation they devour.
7. "On God they have not called." He is comforting the man that groaneth, and chiefly by an admonition, lest by imitating evil men, who ofttimes prosper, they delight in evil doing. There is kept for thee that which to thee hath been promised: their hope is present, thine is future, but theirs is transient, thine sure; theirs false, thine true. For they "upon God have not called." Do not daily such men ask of God? They do "not" ask of God. Give heed, if I am able to say this by the aid of God Himself. God gratuitously will have Himself to be worshipped, gratuitously will have Himself to be loved, that is chastely to be loved; not Himself to be loved for the reason that He giveth anything besides Himself, but because He giveth Himself. He then that calleth upon God in order that He may be made rich, On God doth not call: for upon that He calleth which to himself he willeth to come. ...But now thou wouldest have coffer full, and conscience void: God filleth not coffer, but breast. What do outward riches profit thee, if inward need presseth thee? Therefore those men that for the sake of worldly comforts, that for the sake of earthly good things, that for the sake of present life and earthly felicity, call upon God, do not call upon God.
