Take no part in the unfruitful works of darkness, but instead expose them. For it is shameful even to speak of the things that they do in secret. But when anything is exposed by the light, it becomes visible . (Eph 5:11-13)
Jesus exposed evil. The Light of the World does that. His people are the light of the world and we are to do the same evil-exposing that He did. His Word shows us the pattern:
Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and the plate, but inside they are full of greed and self-indulgence. (Matthew 23:25)
Alexander the coppersmith did me great harm; the Lord will repay him according to his deeds. Beware of him yourself, for he strongly opposed our message. (2 Timothy 4:14-15)
I have written something to the church, but Diotrephes, who likes to put himself first, does not acknowledge our authority. So if I come, I will bring up what he is doing, talking wicked nonsense against us. And not content with that, he refuses to welcome the brothers, and also stops those who want to and puts them out of the church. (3 John 1:9-10)
It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father’s wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. (1 Cor 5:1-2)
Need I go on? This is the pattern of Light exposing evil as God commands. Is it the typical pattern we see in churches now? Hardly.
