The story of the Incarnation is often represented as incredible; but if those who so regard it would only reflect on that doctrine of heredity which the science of recent years has brought into such prominence, if they would only consider what is involved in the obvious truth that, "that which is born of the flesh is flesh," they would see that it was not only natural but necessary that the birth of Jesus Christ should be "on this wise." Inasmuch as "the first man is of the earth, earthy," "the Second Man" must be "of heaven," or He will be no Second Man at all; He will be sinful and earthy like all the others. But all that is needful is met in the manner so chastely and beautifully set forth by our Evangelist, in words which, angelic in their tone and like the blue of heaven in their purity, so well become the angel of the Lord.
Some wonder that nothing is said here of Nazareth and what took place there, and of the journey to Bethlehem; and there are those who are fain even to find some inconsistency with the third Gospel in this omission, as if there were any need to wonder at omissions in a story which tells of the first year on one page and the thirtieth on the next! These Gospels are not biographies. They are memorials, put together for a special purpose, to set forth this Jesus as the Son of God and Saviour of the world. And the special object, as we have seen, of St. Matthew is to set Him forth as the Messiah of Israel. In accordance with this object we have His birth told in such a way as to bring into prominence those facts only in which the Evangelist specially recognised a fulfilment of Old Testament prophecy. Here again the names give us the main thoughts. Just as Abraham, David, Babylon, suggest the main object of the genealogy, so the names Emmanuel, Jesus, suggest the main object of the record of His birth. "All this was done that it might be fulfilled which was spoken by the prophet."
The first name mentioned is "Jesus." To understand it as St. Matthew did, we must bear in mind that it is the old historic name Joshua, and that the first thought of the Hebrew mind would be, Here is One who shall fulfil all that was typified in the life and work of the two Old Testament heroes who bore that name, so full of hopeful significance.[2] The first Joshua was Israel's captain on the occasion of their first settlement in the land of promise after the bondage in Egypt; the second Joshua was Israel's high priest at their second settlement in the land after the bondage in Babylon. Both were thus associated with great deliverances; but neither the one nor the other had given the rest of full salvation to the people of God (see Heb. iv. 8); what they had done had only been to procure for them political freedom and a land they could call their own,--a picture in the earthly sphere of what the Coming One was to accomplish in the spiritual sphere. The salvation from Egypt and from Babylon were both but types of the great salvation from sin which was to come through the Christ of God. These or such as these must have been the thoughts in the mind of Joseph when he heard the angel's words: "Thou shalt call His name Joshua; for it is He that shall save His people from their sins."
Joseph, though a poor carpenter of Nazareth, was a true son of David, one of those who waited for the salvation of Israel, who had welcomed the truth set forth by Daniel, that the coming kingdom was to be a kingdom of the saints of the Most High,--not of political adventurers, as was the idea of the corrupt Judaism of the time; so he was prepared to welcome the truth that the coming Saviour was One who should deliver, not from the rule of _Rome_, but from the guilt and power and death of _Sin_.
