One of the great truths of the Bible is that Jesus died for our sins, not for His own. Jesus was totally sinless. This is one of the major differences between Christianity and the religions of the world. No other religious leader has ever claimed to be sinless, therefore no other religious leader is even in the same class with Jesus.
Also, no other religious leader has ever given his life in sacrifice to atone for the sins of others. It wouldn't have done any good if one had. Since the religious leaders were sinners themselves, their lives weren't worth any more than any other sinner. But, since Jesus was the sinless Son of God, His life was worth more than all of humanity throughout the ages.
Every detail of Christ's death, burial, and resurrection was already prophesied in the bible before it happened. All the events of Jesus' life, death, and resurrection had fulfilled scripture.
God's Word is the ultimate authority and only through His Word can we receive faith to be born again. We must preach the Word, not experiences. Experiences are only useful to illustrate that God's Word is true. Jesus is alive from the dead. His tomb is empty. Jesus provided us with the ultimate verification of His authority. He arose from the dead.
