I met a man who lived on the Potomac River. When the space shuttle, Discovery, flew by on a hot sunny day, the man rushed into his yard with his iphone. He hastily pointed the camera into the sky and took a picture. He showed me the picture. As a result of failing to switch the camera’s mode it was a picture of himself gazing into the sky.
This is how many attempt to build a picture of God; they refuse to allow that God has revealed himself in creation and in his word and, instead, they abstract from themselves a god or gods. If the starting point is self, then that is all the picture will show. But if the starting point is the self-revelation of God himself then the camera is pointing the right way.
