The New Testament calls us to grow up into maturity in Christ, to be conformed to the image of Christ, and to seek the mind of Christ. To have the mind of Christ means that we think like Christ so that we act like Christ. The New Testament calls us to the imitatio Christi—the imitation of Christ—and the Apostle Paul sets forth the idea that we are to imitate Christ as Christ imitated the Father. How did Jesus do that? By His perfect obedience.
