“Proving what is acceptable unto the Lord.”
King James Version (KJV)
5:8 Ye were once darkness - Total blindness and ignorance. Walk as children of light - Suitably to your present knowledge.
5:9 The fruit of the light - Opposite to the unfruitful works of darkness, #Eph 4:11|. Is in - That is, consists in. Goodness and righteousness and truth - Opposite to the sins spoken of, #Eph 4:25|,&c.
5:11 Reprove them - To avoid them is not enough.
5:12 In secret - As flying the light.
Eph 5:10 Proving what is acceptable unto the Lord. Showing by walking in the light what is acceptable to God.
