The focus of the gospel is not on the inadequacy of mankind (including the transformation), but rather on the glory of God. I am transformed when I live in line with the gospel (Gal. 2:14)—avoiding both legalism and licentiousness—and pursuing the joy found in complete and utter surrender of my unrighteous life in exchange for his righteous life expressed graciously through every aspect of my Christian walk (Gal. 2:20).I often make the gospel about our wretchedness above the mercy and kindness of God. This is dumb. It's also something I'm fighting through (and against) at the moment.
Let's not make the gospel about us. It's all about Jesus.
