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

In John 14:6, Jesus declares, 'I am the way, the truth, and the life: no man cometh unto the Father, but by me.' This clear statement reinforces the belief that Jesus is the unique mediator between God and humanity. The consistent teaching throughout Scripture, including in Acts, affirms that salvation comes solely through faith in Christ's finished work. This exclusivity is rooted in the fact that humanity is dead in trespasses and sins, requiring divine intervention for salvation, which only Jesus provides.
