This Christian claim [of universal validity] is naturally offensive to the adherents of every other religious system. It is almost as offensive to modern man, brought up in the atmosphere of relativism, in which tolerance is regarded almost as the highest of the virtues. But we must not suppose that this claim to universal validity is something that can quietly be removed from the Gospel without changing it into something entirely different from what it is... Jesus' life, his method, and his message do not make sense, unless they are interpreted in the light of his own conviction that he was in fact the final and decisive word of God to men... For the human sickness there is one specific remedy, and this is it. There is no other.
