The self-giving of the incarnation

But if we really take the biblical view of God, then we must think of God the Father as sending the Son into our lost existence, into unutterable humiliation in order to be really one with us. We must think of God as determining himself freely to be our God, directing himself freely to share in the profoundest way in our frail life, in all its limitations and weaknesses, and even in its lostness, all in order to be our God, and to gather us into fellowship with himself. But in this act of unspeakable humiliation, God was not simply using the humanity of Christ as his organ or instrument, while he remained transcendent to it all. He himself actually came, the immutable God, humbling himself to become a creature and to suffer as a creature our judgement and death, and throughout all that to maintain his sovereign freedom and initiative, even when he gave himself up to the death of the cross, in an offering as unreserved in his self-giving as it was majestically omnipotent and free in its act of grace.—T. F. Torrance, Incarnation: The Person and Life of Christ, 227
