How and Why did Jesus influence the world?

Jesus came down to Earth because he was sent by God to redeem humans for our sins. It was his fate to come down unto Earth, simply to be accused at and crucified for the sins of man. People didn't believe him. However, when He rose after 3 days, his disciples especially, were greatly influenced. They saw, which made them believe. These disciples are now a chapter in a part of the Bible. That is how Jesus has positively influenced the World, for the better of mankind.
