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.
Even so, Scripture makes it clear that the cross must remain at the center of the gospel. We cannot move it to the side, and we cannot replace it with any other truth as the heart, center, and fountainhead of the good news. To do so is to present the world with something that is not saving, and that is therefore not good news at all.
