My class enjoys studying the gospels through the eyes of Max Lucado. He presents the lessons in each book in an interesting, challenging, and personal way. The lessons are easy to read with some humor thrown in. They generate a good deal of discussion among those in my class. They also cause self examination in our discussions.
We like this study series as the lessons can be covered in 6-10 weeks by our small group. Rather than being an indepth study of the book of Luke, it picks out key principles that strengthen your faith and your walk with God.
