WCF 16.7.
Works done by unregenerate men, although for the matter of them they may be things which God commands; and of good use both to themselves and others: (2 Kings 10:30–31, 1 Kings 21:27, 29, Phil. 1:15–16, 18) yet, because they proceed not from an heart purified by faith; (Gen. 4:5, Heb. 11:4, 6) nor are done in a right manner,according to the Word; (1 Cor. 13:3, Isa. 1:12) nor to a right end, the glory of God, (Matt. 6:2, 5, 16) they are therefore sinful, and cannot please God, or make a man meet to receive grace from God: (Hag. 2:14, Tit. 1:15, Amos 5:21–22, Hosea 1:4, Rom. 9:16, Tit. 3:5) and yet, their neglect of them is more sinful and displeasing unto God. (Ps. 14:4, Ps. 36:3, Job 21:14–15, Matt. 25:41–43, 45, Matt. 23:23)
