It is far better to tell Christians that they have been changed than it is to tell them to change. Only then can they live by faith in what Jesus did, rather than by faith in what they must do. That distinction is crucial! Marveling at the change that took place for them and to them is the only way of hope for the uncertainty of their days in this world.
Get that order out of order (which we all-too-often have), and life by works is the unavoidable result. That won’t work. Not for anybody. It’s not supposed to. Life is by faith that Jesus was successful for you and with you, and that He will continue to be—that’s the gospel. Stay in it, because it’s fantastic news! And that’s where the power of God is for you and me.
Stay there, and works will follow.
Romans 1:16 For I am not ashamed of the gospel, because it is the power of God that brings salvation (soundness) to everyone who believes: first to the Jew, then to the Gentile. (Parenthesis mine.)
1 Corinthians 1:18 For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.
