The gospel is all about God’s completion of all the work and our receiving His work’s benefits by our faith alone. It is all about God rescuing us, not about Him just providing a way for us to rescue ourselves. Overemphasis on the “turn from your sins” message takes the glory away from Christ that He so completely earned on the cross. That leads to boasting in the flesh, and “far be it from me that I should boast except in the cross of our Lord Jesus Christ.” (Galatians 6:14)
