He could have remained far above us in his holy heaven. Angels attend him and perfection surrounds him, but he did not remain removed and aloof; God came down to us. In fact, he actually became one of us. He shared in our pain, our sweat, our grime.
He could have written us off. He could have decided we were not worth the effort. If we destroyed each other, that was our problem. Love compelled him. Love could not sit idle while humanity continued it's steady slide into self destruction. Love had to intervene.
He could have just sent us a bible and left it at that, but that would not do. He could have sent an angel or a prophet but he did more than that; he came in person. He did not want to just tell us the message of salvation he decided to be our salvation. He wanted us to see, feel and know clearly that he loves us and wants us to be with him.
Behold, the Word made flesh. God among us.
