Ephesians 5:9-13

(for the fruit of the Spirit is in all goodness and righteousness and truth;) proving what is acceptable unto the Lord. And have no fellowship with the unfruitful works of darkness, but rather reprove them. For it is a shame even to speak of those things which are done of them in secret. But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.
