This question looms very large in the minds of modern men. The burden of the question seems to rest heavily even upon many who still accept the miracles of the New Testament. The miracles used to be regarded as an aid to faith, it is often said, but now they are a hindrance to faith; faith used to come on account of the miracles, but now it comes in despite of them; men used to believe in Jesus because He wrought miracles, but now we accept the miracles because on other grounds we have come to believe in Him.
A strange confusion underlies this common way of speaking. In one sense, certainly, miracles are a hindrance to faith—but who ever thought the contrary? It may certainly be admitted that if the New Testament narrative had no miracles in it, it would be far easier to believe. The more commonplace a story is, the easier it is to accept it as true. But commonplace narratives have little value. The New Testament without the miracles would be far easier to believe. But the trouble is, it would not be worth believing. Without the miracles the New Testament would contain an account of a holy man—not a perfect man, it is true, for He was led to make lofty claims to which He had no right— but a man at least far holier than the rest of men. But of what benefit would such a man, and the death which marked His failure, be to us? The loftier be the example which Jesus set, the greater becomes our sorrow at our failure to attain to it; and the greater our hopelessness under the burden of sin. The sage of Nazareth may satisfy those who have never faced the problem of evil in their own lives; but to talk about an ideal to those who are under the thralldom of sin is a cruel mockery. Yet if Jesus was merely a man like the rest of men, then an ideal is all that we have in Him. Far more is needed by a sinful world. It is small comfort to be told that there was goodness in the world, when what we need is goodness triumphant over sin. But goodness triumphant over sin involves an entrance of the creative power of God, and that creative power of God is manifested by the miracles. Without the miracles, the New Testament might be easier to believe. But the thing that would be believed would be entirely different from that which presents itself to us now. Without the miracles we should have a teacher; with the miracles we have a Savior.”
