'That Which Is Good' in the Bible

Did then that which is good become death to me? By no means, but sin; that sin might be made manifest, producing death to me through that which is good, that sin might become exceedingly sinful through the commandment.

Let love be without hypocrisy. Abhor evil, adhere to that which is good,

Let us each please our neighbor in that which is good for edification;

For your obedience has come to all; I rejoice in you therefore, but I wish you to be wise for that which is good, and simple for evil.
