God’s Eternal Covenant of Promise (Galatians 3:15–18) John MacArthur

Summary

This sermon focuses on the core doctrine of salvation by faith alone, highlighting its pivotal role in the Reformation and drawing from the book of Galatians. The speaker contrasts this with the false gospel of faith plus works, referencing biblical covenants and God's promises to Abraham as evidence of God's unilateral, unconditional, and gracious commitment. The practical takeaway is the critical importance of clinging to the true gospel of grace, as any deviation leads to a damning message and the church failing in its mission.
