After having been justified by faith, through the work of the Spirit, the Galatians had become 'bewitched' by the foolish idea that they needed to grow to maturity by their own 'flesh' or human effort. In a similar way, we can easily slip into thinking that the way we continue in the Christian life is different than the way we began. We need this reminder that we are not only justified but also sanctified by faith in the gracious work of God to finish what he started in Christ Jesus.
