The central miracle asserted by Christians is the Incarnation. They say that God became Man. Every other miracle prepares for this, or exhibits this, or results from this. Just as every natural event is the manifestation at a particular place and moment of Nature’s total character, so every particular Christian miracle manifests at a particular place and moment the character and significance of the Incarnation. There is no question in Christianity of arbitrary interferences just scattered about. It relates not a series of disconnected raids on Nature but the various steps of a strategically coherent invasion—an invasion which intends complete conquest and “occupation.” The fitness, and therefore credibility, of the particular miracles depends on their relation to the Grand Miracle; all discussion of them in isolation from it is futile.
