You have grown in the grace and knowledge of our Lord and Savior Jesus Christ. You are not the man or woman you once were. You are more mature than once you were—more like Christ, more in tune with your heavenly Father, more manifestly a child of His care. Your delight in righteousness has developed. Your sensitivity to sin has increased. Your wish to please God is fuller and more finely developed. It’s not just growing up. That cannot account for it all. It is growing up in all things into Him who is the Head, Jesus Christ.
When someone is converted, there is an immediate and radical change. From the inner man outward, everything changes. For some people, perhaps converted from a more openly wicked life, that shift has effects that are obvious to others. Like the Gadarene demoniac, the sinner is now found clothed and in his right mind, and everyone can tell the difference. For others, although the inward shift is equally radical and equally absolute, the outward evidence is not so marked. Perhaps they had lived a more moral life or were brought up under the healthy restraint of a gospel home.
