Why is boasting in our works contrary to the Christian faith?

In Galatians 6:12, Paul highlights that those who wish to make a fair show in the flesh restrict others to the law, thus ensuring they could boast about their accomplishments. This mentality opposes the essence of Christianity, which is that no works can save us or contribute to our standing before God. True faith acknowledges that our salvation is solely due to Christ’s merit, rendering any self-boasting meaningless. As Christ Himself said in John 15:5, "Without Me, you can do nothing," emphasizing our total dependence on Him.
