What is the difference between the gospel and false gospels?

The distinction between the true gospel and false gospels is crucial in understanding biblical salvation. The true gospel reveals God's work in Christ and His grace toward us, as shown in Galatians 1:6-7, where Paul rebukes those who pervert the gospel by adding human works to grace. False gospels often center around human action and merit, suggesting that individuals must contribute something to their salvation, effectively undermining the completed work of Christ. In contrast, the true gospel is about what God has done for us, declaring that 'salvation is of the Lord' (Jonah 2:9), and that His grace is sufficient for our salvation apart from our deeds.
