God did not just tell us what he wanted us to do, nor did he just show us. He could have only sent us messages. In fact, he did send us messages ... for hundreds of years. Through prophets, burning bushes, miracles.
But we didn't get it. So He became one of us. Through the process of incarnation. At times I am glad that I was raised Catholic, because I don't fear those theological terms.
God did not want to just speak to us ... He wanted to be one of us, even if only for a few decades. Such a humbling act of God. He gave up all his power and might to become human. To lower himself.
