Because of our forgetfulness, God has created the physical world to be mnemonic, to help us daily remember that we are not alone, that we are not at the center, that life is not primarily about us, and that there is a grander story than the little stories of our individual lives. Physical things are meant to remind us of the grandeur and glory of the One who created all those things, set them in motion, and keeps them together by the awesome power of his will.
