How does legalism affect the Christian faith?

Legalism represents a significant threat to the integrity of the Christian faith, as it encourages reliance on human effort rather than on the grace of God for salvation. Paul cautioned the Galatians against those who would impose a return to law observance, warning that such actions deny the essence of the gospel, which is rooted in free grace. When Christians stray into legalism, they risk losing sight of the all-sufficient work of Christ and may become overwhelmed by guilt and doubt. True freedom in Christ entails recognizing that our acceptance before God is not dependent on our adherence to the law but solely on the grace afforded to us through Jesus Christ.
