How do we know Jesus is the only way to heaven?

John 14:6 records Jesus saying, 'I am the way, the truth, and the life: no man cometh unto the Father, but by me.' Throughout the Bible, salvation is presented as dependent on the name and work of Jesus Christ. Acts 4:10-12 reinforces this, asserting there is no other name under heaven that can save. This claim is supported by the consistent witness throughout the Scriptures that emphasizes the necessity of belief in Jesus for eternal life, showcasing God's sovereign grace in His redemptive plan.
