Karl Barth (by all accounts a theologian I’d get along famously with), said this:

The Gospel is not a truth among other truths. Rather, it sets a question-mark against all truths. The Gospel is not the door but the hinge. The man who apprehends its meaning is removed from all strife, because he is engaged in a strife with the whole, even with existence itself. Anxiety concerning the victory of the Gospel–that is, Christian Apologetics–is meaningless, because the Gospel is the victory by which the world is overcome. … It [the Gospel] does not require representatives with a sense of responsibility, for it is as responsible for those who proclaim it as it is for those to whom it is proclaimed. It is the advocate of both. … God does not need us. Indeed, if He were not God, He would be ashamed of us. We, at any rate, cannot be ashamed of Him.

What say you?
