'That Which Is Good' in the Bible

Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceedingly sinful.

For I know that in me (that is, in my flesh,) dwells no good thing: for to will is present with me; but how to perform that which is good I find not.

Let love be without hypocrisy. Abhor that which is evil; cleave to that which is good.

For rulers are not a terror to good works, but to the evil. Will you then not be afraid of the power? do that which is good, and you shall have praise of the same:

For your obedience is well known unto all men. I am glad therefore on your behalf: but yet I would have you wise unto that which is good, and innocent concerning evil.
