'Law of God' in the Bible

I have, in fact, a sympathetic pleasure in the law of God; according to the inner man.

Butthanks be unto God! - Through Jesus Christ our Lord. Hence, then, - I myself, with the mind, indeed, am in servitude unto a law of God; but; with the flesh; unto a law of sin.

Inasmuch as, what is preferred by the flesh, is hostile towards God, for, unto the law of God, it doth not submit itself, neither in fact can it. -
