Everything that God knows and thinks is the "mind of God."
Jesus, as the Second Person in the Trinity, is entirely God. He is the entire mind of God, all that God is, entering into the world that He created. The infinite in a finite human body.
This is the essential mystery of the Christian faith; that the infinite becomes incarnate and dwells among us. Going so far as to sacrifice Himself in order to pay the infinite debt created by sin. No one else is infinite, so no sacrifice of humanity could pay the debt. Only God Himself, joining together with humanity in the Second Person could make the infinite sacrifice and repair the rift between man and God.
This is not language, but Christian thought. That's probably enough of an answer (if not too much) for this forum.
