'What is Good' in the Bible

Therefore, did what is good cause my death? Absolutely not! On the contrary, sin, in order to be recognized as sin, was producing death in me through what is good, so that through the commandment, sin might become sinful beyond measure.

For I know that nothing good lives in me, that is, in my flesh. For the desire to do what is good is with me, but there is no ability to do it.

Love must be without hypocrisy. Detest evil; cling to what is good.

The report of your obedience has reached everyone. Therefore I rejoice over you. But I want you to be wise about what is good, yet innocent about what is evil.
