A very Christ-centered survey of the OT. Unique to it's kind in its comprehensive aspect of Christ centerness. An excellent survey. Geisler is an excellent writer, scholar, philosopher, and speaker. You will benefit greatly from his work.
A good introduction for those beginning to study the Old Testament. Geisler provides basic background information for each book (dating, authorship), then gives a summary breakdown of it. Has a few maps and tables which are helpful. For a more in depth Old Testament study get Gleason Archer's OT Survey.
