How do we know that Christ is the only way to heaven?

The exclusivity of Christ as the only path to salvation is a clear tenet in the Christian Scriptures. In Acts 4:12, it is stated that 'there is no other name under heaven given among men whereby we must be saved.' This encapsulates the essence of the gospel message that proclaims Jesus Christ crucified and risen as the sole mediator between God and man. This idea is supported throughout scripture, linking the fulfillment of God's promise of salvation through Jesus alone. The consistent declaration in both the Old and New Testaments confirms this singular point: that only through Christ’s righteousness can one access eternal life; emphasizing the urgency and importance of proclaiming His name to the world.
