Romans 7:22

For I delight in the law of God,.... This an unregenerate man cannot do; he does not like its commands, they are disagreeable to his corrupt nature; and as it is a threatening, cursing, damning law, it can never be delighted in by him: the moralist, the Pharisee, who obeys it externally, do not love it, nor delight in it; he obeys it not from love to its precepts, but from fear of its threatenings; from a desire of popular esteem, and from low, mercenary, selfish views, in order to gain the applause of men, and favour of God: only a regenerate man delights in the law of God; which he does, as it is fulfilled by Christ, who has answered all the demands of it: and as it is in the hands of Christ, held forth by him as a rule of holy walk and conversation; and as it is written upon his heart by the Spirit of God, to which he yields a voluntary and cheerful obedience: he serves it with his mind, of a ready mind freely, and without any constraint but that of love; he delights together with the law, as the word here used signifies; the delight is mutual and reciprocal, the law delights in him, and he delights in the law; and they both delight in the selfsame things, and particularly in the perfect obedience which the Son of God has yielded to it.
