When we talk about growing in Christ it’s important not to romanticize the process or assume it is merely a matter of attitude change. We need to stress the need to be sanctified, but then carefully nuance it. Ed Welch says it best: “Sanctification is like a clumsy, slow walk rather than a light switch that we turn from off to on.” Christian growth is unmistakably painful at times. Like redemptive history, it is filled with uncertainty, doubt, and fears.
Sanctification is that process of slow growth throughout our Christian walk. I think most of II Corinthians 5:17 “therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.”(Esv) and Philippians 1:6 “And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.” (Esv)…At the end “Sanctification” the completed Disciple.
