How do we know Christ is the only way to salvation?

John 14:6 encapsulates the exclusive claim of Jesus Christ when He states, 'I am the way, the truth, and the life: no man cometh unto the Father, but by me.' This verse underscores the sovereignty of Christ in salvation, affirming that He alone is the mediator between God and humanity. Additionally, Acts 4:12 reinforces this exclusivity, declaring, 'Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.' This highlights that salvation comes solely through faith in Jesus, and no other means or entities can secure eternal life.
