The good folks at Crossway Books have released a new book by John Piper on developing a Christian mind entitled Think which can be obtained here.  Many books have been written on developing a Christian mind or worldview, but Piper brings his familiarity with Jonathan Edwards to bear on the topic in that the mind is not divorced from the emotions or will.  In fact, a Christian mind is a one which loves God as well as thinks about him.  Think about that!
