When God became man in Jesus Christ, he did not become other than himself. The incarnation was an act of self-expression not self-abnegation. The humiliation of the Son was not an artifice for the sake of the economy of redemption. The Son as man discloses the God, who by his very nature stoops to bear the sins of his enemies. We worship no other God than the Father whose Son was born of woman by the Holy Spirit.
"The point is that when we have to do with Jesus Christ we have to do with God. His presence in the world is identical with the existence of the humiliated, obedient, and lowly man, Jesus of Nazareth. Thus, the humiliation, lowliness, and obedience of Christ are essential in our conception of God." (Robert Letham, The Holy Trinity, In Scripture, History, Theology, and Worship, P&R, 2004, p. 397).
