Why is holding to the true gospel important for Christians?

The true gospel is central to the Christian faith because it proclaims that salvation is accomplished solely through Jesus Christ's work and not through human effort. When Christians embrace a different gospel, they risk departing from Christ and losing the grace that sustains their faith. The Apostle Paul emphasizes this in Galatians 1:6-9, where he warns against embracing any gospel other than the one he preached, underscoring that to depart from the gospel is to abandon the very source of truth and grace. It is crucial for believers to hold fast to the gospel to ensure that their salvation is anchored in Christ’s completed work, which leads to spiritual security and glory.
