What does Galatians 1:11-12 teach about the origin of the gospel?

In Galatians 1:11-12, the Apostle Paul explicitly states that the gospel he preached was not a product of man’s invention nor learned from human sources, but revealed directly by Jesus Christ. This assertion is vitally important within the Reformed understanding of salvation, illustrating the cornerstone belief that the gospel originates from God and emphasizes His sovereignty in salvation. Paul distinguishes the true gospel from many perversions that arise from human reasoning. By affirming the divine revelation of the gospel, Paul underscores the necessity of adhering to the truth of God's Word alone for salvation, which has profound implications for both individual believers and the church as a whole.
