O wonderful exchange! The Creator of mankind, by taking on a human body, imparts to us his divinity. It is for this wondrous task that the Saviour came into this world. God became a Child of man so that the human race could become children of God. One of our race severed the bond of our divine adoption; one of us had to bind it up again and pay for the sin. No one from the ancient, sick and degenerate race could do it. A new, healthy and noble sprout had to be grafted. He became one of us; but even more than that: one with us. That is precisely the wonderful thing about the human race – that we are all one. If it were otherwise, were we all to exist as independent and separate individuals, then the fall of one could not have brought about the fall of all. Then, on the other hand, the price of sin could probably have been paid for us and charged to us, but his justification would not have passed on to sinners; no vindication would have been possible. But he came to be a mysterious Body with us: he as head, we as members. Let us place our hands in the hands of the divine Child, let us speak our ‘yes’ to his ‘follow me’. Thus we shall be his and the path shall be open for his divine life to pass over upon us.
