Man is not so essentially different from God as to render the Incarnation impossible. God is not totally separated from man by omniscience and omnipotence.
Nowhere does the Bible represent Jesus as a dual character, God united to a man, but God become man, the Word made flesh. When on earth, Christ's divine functions and honours were largely handed over to the Father, and again bestowed by the Father upon the Son after His resurrection from the dead.
Disbelief in the Incarnation robs humanity of the honour put upon it by the Word becoming flesh. Those who believe that Christ was Emmanuel, God manifest in the flesh, are not likely to slight humanity, or to have degrading views of mankind. The Incarnation shows that man has a dignity which God clearly recognizes. If man were a mere animal, born of the dust, like the lower creatures, and sharing their destiny, then one would be astonished that God should care so much for us. But as man is endowed with divine powers for a divine destination, then to recover such a being from ruin and raise him to bliss, is an end worthy of God's condescension, worthy of the Incarnation.
