The Good Master
Like many of the other Phillip Keller books this is an allegory . On one level, It is a story about a South African sheep rancher and his sheep dog, but it is really about how God is the good Master who redeems me from ultimate destruction and desires a personal relationship with me. The spiritual application flows naturally from the story. The arguments aren't forced, but convincing. This is a better devotional than many books claiming to be devotionals.
