T. F. Torrance on the Jewishness of Jesus

Thus the knowledge of God, of Christ, and of the Jews are all bound up inseparably together, so that when at last God came into the world he came as a Jew. And to this very day Jesus remains a Jew while still the eternal Son of God. It is still through the story of Israel, through the Jewish soul shaped by the hand of God, through the Jewish scriptures of the Old Testament and the Jewish scriptures of the New Testament church, the gospel comes to us, and that Jesus Christ is set before us face to face as Lord and saviour. Apart from this Old Testament prehistory and all the biblical revelation through Israel, we would not have the tools to grasp the knowledge of God; apart from the long history of the Jews we would not be able to recognise Jesus as the Son of God; apart from the suffering and agony of Israel we would not understand the cross of Calvary as God's instrument to atone for sin and to enact once and for all his word of love and pardon and grace. Apart from the covenant forged in sheer grace with undeserving and rebellious Israel, and the unswerving faithfulness of the divine love, we would not be able to understand the mystery of our restoration to union with God in Jesus Christ. Apart from the context of Israel we could not even begin to understand the bewildering miracle of Jesus. The supreme instrument of God for the salvation of the world is Israel, and out of the womb of Israel, Jesus, the Jew from Nazareth — yet he was no mere instrument in the hands of God, but very God himself, come in person in the form of a servant, to work our from within our limitations and recalcitrance, and to bring to its triumphant completion, the redemption of mankind, and our restoration to fellowship with the very life of God himself. [Thomas F. Torrance, Incarnation, 53-4.
