He sprang up and went over to where Jesus stood. Jesus asked him. He knew what he needed. And Jesus opened his eyes. To be able suddenly to see when you couldn't see before must be an amazing experience.
Many people experience that in a spiritual way.
They suddenly see what they never saw before. They catch such a glimpse of the kingdom that they see with new vision. They see it all. When that happens they can't stop talking about it. They have this amazing mountain top experience that they want to share with everyone.
