Ephesians 5:6, 11-13:
6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.
11 And have no fellowship with the unfruitful works of darkness, but rather reprove them. [this is not a command for passivity]
12 For it is a shame even to speak of those things which are done of them in secret.
13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.
Failure to speak against evil and passivity–WHAT DOES THE BIBLE SAY? And what did Dietrich Bonhoeffer say?
Isaiah 58:1: Cry aloud, spare not, lift up thy voice like a trumpet,..show their transgression, and their sins
They are waxen fat, they shine: yea, they overpass the deeds of the wicked: they judge not the cause, the cause of the fatherless, yet they prosper; and the right of the needy do they not judge. Jeremiah 5
