We see here the Apostle Paul warning the Galatians of there being no room for error when it comes to the gospel, because mixing law and grace endangers people’s eternal destiny. Paul is astonished that they were so quickly turning from God’s grace to a different gospel—one that added law‑keeping to faith and thus perverted the true message of salvation. Paul insists that anyone who preaches anything other than the gospel he received directly from Christ, that messenger must be rejected as accursed. True servants of Christ are to stand firmly for the pure gospel of grace, seeking to please God rather than people.
