'That Which Is Good' in the Bible

Did then that which is good become death to me? Far be it! but sin; that it might become manifest as sin, causing death to me by means of that which is good; that sin by means of the commandment might become exceedingly sinful.

For I know that there dwelleth not in me, that is, in my flesh, any good thing; for to desire is present with me, but not to perform that which is good.

Let your love be unfeigned. Abhor that which is evil, cleave to that which is good.

For rulers are not a terror to good works, but to the evil. Wouldst thou then not be afraid of the government? Do that which is good, and thou wilt have praise from it;

For your obedience hath become known to all. Over you, then, I rejoice; but I would have you wise as to that which is good, and simple as to that which is evil.
