God's Fire is the awesome story of the most human of experiences, the birth and establishment of a great god. The Hebrew Exodus from Egypt is here viewed as a well-led, well-managed expedition, both aided and beset by horrendous natural conditions. Earth was in those days undergoing a devastating encounter with a comet. An abundance of evidence is presented to delineate, and also integrate, the various effects of this long-drawn-out cosmic catastrophe. Emanating from the comet-Earth interaction were multitudinous electrical phenomena, accepted in principle by modern science, but hitherto incredible as history. On center-stage in this dramatic setting looms the figure of Moses, who is made understandable by the psychiatric method of the Author, but at the same time is grandiose beyond analytic language in his achievements. A score of great inventions are shown to be of Moses, including the electric Ark of the Covenant and, the greatest of them all, Yahweh himself. God's Fire is the literal nature of Yahweh.
