Psalms 7:9

"But let the wickedness of sinners be consummated" [Psalm 7:9]. He says, "be consummated," be completed, according to that in the Apocalypse, "Let the righteous become more righteous, and let the filthy be filthy still." [Revelation 22:11] For the wickedness of those men appears consummate, who crucified the Son of God; but greater is theirs who will not live uprightly, and hate the precepts of truth, for whom the Son of God was crucified. "Let the wickedness of sinners," then he says, "be consummated," that is, arrive at the height of wickedness, that just judgment may be able to come at once. But since it is not only said, "Let the filthy be filthy still;" but it is said also, "Let the righteous become more righteous;" he joins on the words, "And You shall direct the righteous, O God, who searches the hearts and reins." How then can the righteous be directed but in secret? When even by means of those things which, in the commencement of the Christian ages, when as yet the saints were oppressed by the persecution of the men of this world, appeared marvellous to men, now that the Christian name has begun to be in such high dignity, hypocrisy, that is pretence, has increased; of those, I mean, who by the Christian profession had rather please men than God. How then is the righteous man directed in so great confusion of pretence, save while God searches the hearts and reins; seeing all men's thoughts, which are meant by the word heart; and their delights, which are understood by the word reins? For the delight in things temporal and earthly is rightly ascribed to the reins; for that it is both the lower part of man, and that region where the pleasure of carnal generation dwells, through which man's nature is transferred into this life of care, and deceiving joy, by the succession of the race. God then, searching our heart, and perceiving that it is there where our treasure is, that is, in heaven; searching also the reins, and perceiving that we do not assent to flesh and blood, but delight ourselves in the Lord, directs the righteous man in his inward conscience before Him, where no man sees, but He alone who perceives what each man thinks, and what delights each. For delight is the end of care; because to this end does each man strive by care and thought, that he may attain to his delight. He therefore sees our cares, who searches the heart. He sees too the ends of cares, that is delights, who narrowly searches the reins; that when He shall find that our cares incline neither to the lust of the flesh, nor to the lust of the eyes, nor to the pride of life, [1 John 2:16] all which pass away as a shadow, but that they are raised upward to the joys of things eternal, which are spoilt by no change, He may direct the righteous, even He, the God who searches the hearts and reins. For our works, which we do in deeds and words, may be known unto men; but with what mind they are done, and to what end we would attain by means of them, He alone knows, the God who searches the hearts and reins.
