The greatest witness for Jesus Christ that I know anything about in the city of Dallas is not a preacher. He's an ophthalmologist. He was in the power structure of an evangelical church for twelve years and never led anybody to Jesus Christ. A group of college kids came along one day and said, "Hey, Doc, are you sharing your faith?"

The doctor said, "No, as a matter of fact, I'm not. I don't even know how to go about it."

They said, "We've got a little training program. How about getting involved in it?"

He said, "Count me in."

They taught him how to share his faith.

This guy leads people to Christ as if it's going out of style: I was way out in a remote section of India, and I use this story as an illustration, but I didn't use his name, figuring nobody knew Dr. Jack Cooper. When I finished, a doctor came up and said, "You were talking about Jack Cooper weren't you?"

I said, "How did you know?"

He said, "I went to medical school in Dallas. While I was there, I went to see Dr. Cooper about my eyes. He led me to Christ and discipled me all the way through medical school."

Today that doctor is the only licensed neurosurgeon in that part of India. He has absolutely unbelievable impact for Jesus Christ. He will tell you it started in the office of a Dallas doctor who knew why he was here instead of in heaven.
