The title of this book comes from Ephesians 4:1: "I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called" (ESV). When people respond to the call of the gospel they are put into Christ, and being "in Him," they are graciously given every spiritual blessing in heavenly places (Eph. 1:3). But how tragic it is that most believers are falling far short of living in a way that corresponds to these spiritual riches. The admonition to the Corinthian church would also indict modern mainstream Christianity: "And I, brethren, could not speak to you as to spiritual people but as to carnal [fleshly], as to babes in Christ. I fed you with milk and not with solid food; for until now you were not able to receive it, and even now you are still not able; for you are still carnal. For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men?" (1 Cor. 3:1-3).

Someone observed, "Our most serious failure today is the inability to provide effective practical guidance as to how to live the life of Jesus." This book seeks to give practical guidance for living a Christ centered life.
