This best-seller goes to the basics of the Christian life -- the cross of Christ, faith, purpose, discipleship and more. It will help new believers build their lives on the solid foundation of Jesus Christ. Day by day during my devotional time I read at least one section and found the book to contain one of the most practical approaches to the various areas of my spiritual life that I have ever read. I asked others to read it, and they confirmed my impressions. The various parts of the book were originally prepared as short letters and were sent to a number of interested friends.
