While we are genuinely new in Christ, we are not yet completely new in Christ. There is still a seed of rebellion from Adam in us, the temptations of the world around us, and the snares of the devil set for us. In this life we continually grow to live out our new identity has new people in Christ through a process called sanctification. In this process we learn more about Jesus and become more like him by the power of the Holy Spirit as we believe the Bible truths outlined in this chapter and act upon them in faith.
One day, we will die. If we die in Christ, we are made fully, completely, unchangingly and eternally new, what theologian’s call glorification. On that day, your faith will be sight as you see the risen and reigning Jesus face-to-face. On that day, everyone in Christ will be made completely perfect as together we rise like Jesus to be like him forever. In Christ, you are new.
