Integrity matters. If you want to serve as a testimony to Christian ethics, then you’re actually going to need to hold them, and that means holding them with consistency. Hypocrisy and double-standards will effectively serve to mute your witness.
It’s hard to cry out against a sin in one instance when, in another instance, you’ve excused, blown-off, or chosen to overlooked that sin.
What if the sort of “power” and influence Jesus intended for his followers wasn’t one of ends-justify-the-means ethical compromise and political power-plays, but witness to a “revolutionary”-like ethic like that of Mt 5-7, with all the integrity, lowliness, and self-sacrifice involved therein (5:13-16)?
Many advocate ethical compromise for the sake of “the greater good” (or “the lesser of two evils”). But what shall it profit the church if it gains a whole election but loses its witness? What if the church’s witness is the actual means of its impact?
