From Greg Gilbert’s What Is the Gospel:
But really, we should just face it. The message of the cross is going to sound like nonsense to the people around us. It’s going to make us Christians sound like fools, and it most certainly is going to undermine our attempts to “relate” to non-Christians and prove to them that we’re just as cool and harmless as the next guy. Christians can always get the world to think they are cool–right up to the moment they start talking about being saved by a crucified man. And that’s where coolness evaporates, no matter how carefully you’ve cultivated it.
