Jesus alone is the way of salvation. CH Spurgeon said,
True salvation is not to be found through the mere reception of any creed, however true or scriptural. Mere “head notion” is not the road to heaven. “You must be born again,” means a great deal more than that you must believe certain dogmas. The study of the Bible cannot save you! You must press beyond this; you must come to the living, personal Christ, or else your acceptance of the soundest creed cannot avail for the salvation of your soul. Salvation lies in Jesus only!
Philip Graham Ryken author of "Is Jesus the Only Way?" wrote,
Authentic, biblical Christianity has always been an exclusive religion. This became apparent during the Roman Empire. When the Emperor Alexander Severus heard about Christianity, he placed an image of Christ beside the other gods in his private chapel, just to be safe. The Romans were happy to welcome Jesus into their pantheon. What the Romans couldn’t understand was why Christians refused to reciprocate. If the emperor was willing to worship Christ, why weren’t Christians willing to worship the emperor? Yet the early Christians insisted that in order to worship Christ at all, they had to worship Christ alone. They were even willing to stand up for this conviction by playing “Christians and lions” at the Colosseum.
John Bunyan author of "Grace Abounding" wrote,
But I observed that, although I was such a great sinner before conversion, God never burdened me heavily with the guilt of sins committed while I was in ignorance. He only showed me that I was lost if I did not have Christ because I had been a sinner. I saw that I needed a perfect righteousness to present me without fault before God, and this righteousness was nowhere to be found but in the person of Jesus Christ.
