" The fact is that without God, we cannot know God. For a start, we are incapable of knowing God by ourselves, so he has to disclose himself—in revelation. But beyond that, God is a person and not an object, so if we are to know him, he must keep on showing himself to us—in relationship. Knowing God therefore begins and ends with God, and it is a gift whose name is grace. "
