Why must we ensure we are preaching the true gospel?

Paul cautions in Galatians 1:8 that if anyone preaches a different gospel than what was received, they should be accursed. This seriousness underscores the importance of fidelity to the true gospel, as it alone reveals God’s plan of salvation through Christ. A false gospel may focus on human merit or experiential faith rather than the redemptive work of Christ. In a world filled with varying interpretations of the gospel, it is imperative for believers to adhere strictly to the biblical message that highlights God's sovereignty and grace in salvation.
