'Obedience' in the Bible

But he who looks carefully into the perfect law, the law of liberty, and faithfully abides by it, not having become a [careless] listener who forgets but an active doer [who obeys], he will be blessed and favored by God in what he does [in his life of obedience].

So too, faith, if it does not have works [to back it up], is by itself dead [inoperative and ineffective].

But someone may say, “You [claim to] have faith and I have [good] works; show me your [alleged] faith without the works [if you can], and I will show you my faith by my works [that is, by what I do].”

You see that a man (believer) is justified by works and not by faith alone [that is, by acts of obedience a born-again believer reveals his faith].

For just as the [human] body without the spirit is dead, so faith without works [of obedience] is also dead.
