He starts off each chapter with a specific promise from Scripture. As expected, each chapter can stand on its own, but the overarching theme is that God keeps his promises, and that gives us hope. He unsuccessfully keeps trying to push the "we are people of the Promise" theme, as if to inspire us, but I don't think it works. Nice try, though. It may have worked if he devoted a poetic chapter to it first, a tear-jerker.
All in all, Max Lucado does it again. Good work, but nothing that really stands out from his other works.
