'That Which Is Good' in the Bible

Was that, then, which is good made death unto me? God forbid. Nay, sin was death unto me, that it might appear: how that sin by the means of that which is good, had wrought death in me: that sin which is under the commandment, might be out of measure sinful.

For I know that in me, that is to say, in my flesh, dwelleth no good thing. To will is present with me: but I find no means to perform that which is good.

Let love be without dissimulation. Hate that which is evil, and cleave unto that which is good.

for your obedience extendeth to all men. I am glad no doubt of you. But yet I would have you wise unto that which is good. And to be innocent as concerning evil.
