The story he tells is supposed to inspire people to become Christians that night. They have an alter call and he counts and celebrates the number of souls that have been saved that night. But in all this, he doesn't validate his own experience, poor fella. He expects people to become Christians in a totally different way than he did. He does not realize his own experience is the human experience.
Salvation takes time.
We all need time. It takes time to learn. It takes time to hear God. The Grace of God gives us this time. Grace strikes us when we are in great pain and restlessness.
