For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel! (1 Cor. 9:16)

And have no fellowship with the unfruitful works of darkness, but rather reprove them. (Eph. 5:11)

But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. (Eph. 5:13)
