The gospel is purely by grace as it declares what God has done through Christ, not what we must do.
The purity of the gospel is rooted in the doctrine of grace, where salvation is presented as an unmerited gift from God available through faith in Jesus Christ. Any deviation that suggests human effort or law observance diminishes the gospel's essence. In Galatians 2, Paul confronts false teachers who would bind believers under a legalistic system, arguing that such a yoke is opposed to the freedom found in Christ. The gospel's message of justification through grace highlights God's sovereign will and action in granting salvation, which is not contingent upon our works but grounded in Christ's atonement. Therefore, it stands as an essential truth for all Christians to believe and uphold.
