7 “On God they have not called.” He is comforting the man that groans, and chiefly by an admonition, lest by imitating evil men, who ofttimes prosper, they delight in evil doing. There is kept for you that which to you has been promised: their hope is present, yours is future, but theirs is transient, yours sure; theirs false, yours 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 gives anything besides Himself, but because He gives Himself. He then that calls upon God in order that He may be made rich, on God does not call: for upon that He calls which to himself he wills to come....But now you would have coffer full, and conscience void: God fills not coffer, but breast. What do outward riches profit you, if inward need presses you? 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.
