>God presented in Exodus is simply an evil god.
You might find interesting the work of Tillich
especially Love, Power, and Justice
where he develops the idea [and this is a radical paraphrase] that the forgiving, healing sort of Love that Christians talk about from the New Testament standpoint, and the (apparently) "evil god" of Exodus, where Justice was front and center, are, in fact, flip sides of the Power coin.
Small book, but an intellectual bagel if ever I chewed one.
