Remarkable Record of Job


Book Description

Far from a myth or fable, the majestic Book of Job stands forever as a genuine historical account of a man assaulted by the accuser, Satan, and redeemed by a loving God. The author asserts further that Job's ancient account (possibly the oldest book in the Bible, apart from Genesis) is scientifically reliable, touching on aspects of nature that prove man's early knowledge of the universe was more highly sophisticated than many believe today. While this commentary emphasizes that we are not told in the Book of Job why humans suffer, there is sufficient evidence to help us understand that God is indeed interested in us.
