The Book of Job contains one solution to the Problem of Evil. It posits that God's program is not to make human life easy, i.e. he is not omnibenevolent in the modern suburban Christian sense. The God of Job intends to test humanity for his own inscrutable purposes, and that Satan is his helpmate in this. That's damn unsatisfying, even sacreligious, if you were brought up to believe in an omnibenevolent God -- it amounts to making God and Satan equals, even partners in crime. However, this viewpoint turns the Problem of Evil from a pat (and honestly, rather trite) refutation of the Abrahamic God into an interesting theological tool for discussing the nature of that God.
