The Son of God is the body of God. It is a physical body in which God dwelt among His people. This physical body did not have its beginning in heaven. Rather, it began when God overshadowed Mary and she conceived a child. This child is the Son of God. It is the body that God created, born of a woman.

“He was in the world, and the world was made by him, and the world knew him not. He came unto his own, and his own received him not...
