“The Son of man came.” Strange the errand, and unique as the blessed Person who undertook it. Thus to come he stooped from the highest throne in glory down to the manger of Bethlehem; and on his part it was voluntary. We are, as it were, thrust upon the stage of action; it is not of our will that we have come to live on this earth. But Jesus had no need to have been born of the virgin. It was his own consent, his choice, his strong desire, that made him take upon himself our nature, of the seed of Abraham. He came voluntarily on an errand of mercy to the sons of men.
