'I am _come_ into the world.' There has been a Man who chose to be born. There has been a Man who appeared here, not 'of the will of the flesh, nor of the will of man,' but by His own free choice. He willed to take upon Him the form of humanity. Now the voluntariness of the entrance of Jesus Christ into the conditions of our human life is all-important for us, for it underlies the whole value of that life and its whole power to be blessing and good to us. It underlies, for instance, the personal sinlessness of Jesus Christ, and hence His power to bring a new beginning of pure and perfect life into the midst of humanity. All the rest of mankind, knit together by that mysterious bond of natural descent which only now for the first time is beginning to receive its due attention on the part of men of science, by heredity have the taint upon them. And if Jesus Christ is only one of the series, then there is no deliverance in Him, for there is no sinlessness in that life. However fair its record may seem on the surface, there is beneath, somewhere or other, the leprosy that infects us all. Unless He came in another fashion from all the rest of us, He came with the same sin as all the rest of us, and He is no deliverer from sin. Rather He is one of the series who, like the melancholy captives on the road to Siberia, each carries a link of the hopeless chain that binds them all together. But, if it be true that of His own will He took to Himself humanity, and was born as the Scripture tells us He was born, His birth being His 'coming' and not His being brought, then, being free from taint, He can deliver us from taint, and, Himself unbound by the chain, He can break it from off our necks. The stream is fouled from its source downwards, and flows on, every successive drop participant of the primeval pollution. But, down from the white snows of the eternal hills of God, there comes into it an affluent which has no stain on its pure waters, and so can purge that into which it enters. Jesus Christ willed to be born, and to plant a new beginning of holy life in the very heart of humanity which henceforth should work as leaven.
