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.
— C. S. Lewis, Miracles
I pray because the need flows out of me all the time, waking and sleeping. It’s doesn’t change God. It changes me.
To be ignorant and simple now — not to be able to meet the enemies on their own ground, would be to throw down our weapons, and to betray our uneducated brethren who have, under God, no defense but us against the intellectual attacks of the heathen. Good philosophy must exist, if for no other reason, because bad philosophy must be answered . . . The learned life then, is for some, a duty.
God could, had He pleased, have been incarnate in a man of iron nerves, the Stoic sort who lets no sigh escape him. Of His great humility He chose to be incarnate in a man of delicate sensibilities who wept at the grave of Lazarus and sweated blood in Gethsemane. Otherwise we should have missed the great lesson that it is by his will alone that a man is good or bad, and that feelings are not, in themselves, of any importance. We should also have missed the all-important help of knowing that He has faced all that the weakest of us face, has shared not only the strength of our nature but every weakness of it except sin. If He had been incarnate in a man of immense natural courage, that would have been for many of us almost the same as His not being incarnate at all.
