'That Which Is Good' in the Bible

But glory and honour and peace be to every man who doeth that which is good, to the Jew first and also to the Greek:

Did then that which is good become fatal to me? God forbid. But sin, that it might appear sin by that which was good [in itself], was the cause of death to me; that sin through the commandment might become transcendantly sinful.

For I know that there dwelleth not in me (that is, in my flesh) any good thing: for to will is present with me; but how to perform that which is good I find not.

Let love be undissembled. Abhor that which is evil; cleave to that which is good.

For rulers are not a terror to good works, but to evil. Wilt thou then not be afraid of the power? Do that which is good, and thou shalt have praise from it:

Let every one of us gratify his neighbour in that which is good for his edification.
