In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence. Although he was a son, he learned obedience through what he suffered. And being made perfect, he became the source of eternal salvation to all who obey him, being designated by God a high priest after the order of Melchizedek (Hebrews 5:7-10).
Every world religion has a founder. Islam has Mohammad. Mormonism has Joseph Smith. Christianity, which is only a world religion based on man's category, has Jesus Christ. Jesus came in the flesh to be the founder of salvation because He is the source of eternal life for all who believe in Him. John 3:16-18 says, "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God " (John 3:16-18).
He suffered in our place not only in His death on the cross, but also through living a perfect life. He knew no sin yet God crushed in him on the cross. The Bible says, "For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God" (2 Corinthians 5:21). Isaiah wrote, "Yet it was the will of the LORD to crush him; he has put him to grief; when his soul makes an offering for guilt, he shall see his offspring; he shall prolong his days; the will of the LORD shall prosper in his hand" (Isaiah 53:10).
Jesus did not come just be an example, but he came to be the founder of our salvation. No other world religion founder suffered for their followers for their sin, but Jesus did. That is why He is "the way, and the truth, and the life" and no one comes to the Father except through Him (John 14:6).
