Why is Jesus different from other world leaders?

Thank you for the question.
If I were to in short say what ultimately makes Jesus different, is that He alone could do what He did to save the mankind from the problem of sin. Jesus alone provides a solution. No other religious / political leader has been able to do what He did, or make the claims that He made, that He Himself was the only way to heaven.
You'll be able to find more about the Uniqueness of Jesus in the article written by Norman Geisler. Do read it in the link below.
