Ephesians 5:11

No fellowship. Not only will they not participate in unfruitful works, they will not countenance them nor have any sympathy with them.

Unfruitful. That is, as far as bringing forth good fruit is concerned. Compare Gal. 5:19-21 on the “works of the flesh.”

Reprove. Gr. elegcho, “to refute,” “to convict,” “to expose.” Compare the use of the word in Luke 3:19; John 3:20; 8:9; 16:8. By word and life Christians should be a continuous rebuke to the world of evil. It is not sufficient to “have no fellowship” with the works of evil; they must be reproved. The Christian cannot be neutral, a passive observer in the face of wickedness; he must be aggressive in exposure and denunciation of sin. Sympathy with afflicted men must not degenerate into an easygoing indifference or sentimental tolerance, otherwise it will be hard to show that we have “no fellowship” with the works of darkness.
