Book excerpt: Many Christians evaluate their lives and ask the same questions: Am I doing enough? Have I shown enough discipline, enough dedication, or enough effort? Would praying and reading my Bible more help meovercome . . . remove . . . have . . .? You may feel that you put so much effort into improving your Christian life with no apparent fruit. Sins you thought would have been easier to overcome are still plaguing your daily life.You are not alone, and you are not crazy! Many Christians today live on this sort of performance-based treadmill, running fast and getting nowhere. Trying harder and doing more haven't produced assurance or victory over sin. You're exhausted. You feel empty and fake inside. You feel guilty for merely wanting to just coast, to give in, to stop trying. The foundation of Christianity is faith. And the foundation of the Christian faith, we will argue in this primer, is rest. In this book, Jon Moffitt, Jimmy Buehler, and Justin Perdue explain how weary pilgrims can find rest in Jesus Christ.
