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.
