Toward the end of the Book of Revelation, the author describes two visions of things to come: one is a vision of heaven in which there are "flashes of lightning, rumblings, peals of thunder, and a violent earthquake" (16:18), and the other is a vision of the earth in which God will dwell and will "wipe away every tear" from the human eyes (21:3-4). In the biblical vision, God is the unknown and unknowable and, at the same time, an intimate personal friend. Both are true, yet how both can be true at the same time remains a mystery. At the heart of the Christian experience of God there is a mystery, and the only possible response to such a mystery is worship.
