How do we know that Jesus is the only way of salvation?

The doctrine that Jesus is the only way of salvation is grounded in Scriptural affirmations such as Isaiah 43:11: 'I, even I, am the Lord, and beside me there is no savior.' Jesus reinforced this truth when He declared in John 14:6, 'I am the way, the truth, and the life; no one comes to the Father except through me.' This exclusive claim emphasizes that salvation cannot be found in any other being or through any other means, making it imperative for believers to understand that Christ's unique role as Savior is central to God's redemptive plan.
