But what are good works?

Only those which proceed from a true faith, (a) are performed according to the law of God, (b) and to his glory; (c) and not such as are founded on our imaginations, or the institutions of men. (d)

(a) Rom.14:23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin. (b) Lev.18:4 Ye shall do my judgments, and keep mine ordinances, to walk therein: I am the LORD your God. 1 Sam.15:22 And Samuel said, Hath the LORD as great delight in burnt offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams. Eph.2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. (c) 1 Cor.10:31 Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God. (d) Deut.12:32 What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it. Ezek.20:18 But I said unto their children in the wilderness, Walk ye not in the statutes of your fathers, neither observe their judgments, nor defile yourselves with their idols: Ezek.20:19 I am the LORD your God; walk in my statutes, and keep my judgments, and do them; Isa.29:13 Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men: Matt.15:7 Ye hypocrites, well did Esaias prophesy of you, saying, Matt.15:8 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. Matt.15:9 But in vain they do worship me, teaching for doctrines the commandments of men.
