So often we are rather brisk and even crude in our witnessing. Because we find it difficult, generally when we do it we are very amateurish. We do it so abruptly and in such a way that often it offends people. We need to be led by the Spirit of God.
I believe that the finest kind of evangelism today is prayer evangelism. I mean that we should begin by praying for an individual. Then the day will come when we need to put legs on the prayer. Ask God to lead you. Friend, I know that He will lead you. If you have been praying for a loved one, or a friend, or a stranger, don't just go to him in your own strength and in the power of the flesh. If you do, you will fail. Let God be the One to lead you.
When I was a student in college, I was very zealous to be a witness for God, but I was rather timid about it, and, very frankly, I wanted to be sure I had the leading of the Holy Spirit. I didn't have any money for bus or train fare, so I did a lot of hitchhiking. One time when I was out on the highway, a man in a brand new Model A Ford drove by and stopped fifty yards past me. Then he motioned for me to come on and get in. He said that he always looked over a hitchhiker before he picked one up. He introduced himself and told me he was a salesman for drug companies. He was going all the way to Memphis and he would be glad to take me all the way, but he did need to stop at several drug stores on the way to get his orders from them.
As we rode along, we talked of everything under the sun. Under my breath I was praying, "Lord, I'd like to witness to this man, but You will have to open the door for me. I'm not going to broach the subject because if I do, he'll think he has some religious nut in the car with him. If I open the door, he will probably open the car door and tell me to get out." So we rode along some more and just talked and talked.
We got about sixty miles from Memphis and we had run out of conversation. There was a lull, and I was still praying, "Lord, we're getting near Memphis and there still hasn't been a door open for me. I'm not going to open it because I'm afraid he'll throw me out. You open the door for me if You want me to witness." We rode on for about ten more minutes, and then out of a clear sky he said, "You know, my wife and I went to church yesterday." He looked at me and laughed, and I laughed. Then he said, "I don't go very often. But that preacher said the funniest thing. He said Jesus was coming to this earth again. What do you think about that?"
Well, friend, I told him. Then I told him all about the first coming of the Lord Jesus. Finally I said, "The second coming of Christ means nothing to you now. You've got to come to Christ and accept what He did for you the first time He came if you are to have an interest in His second coming." This man was wide open. He drove me to the dormitory where I stayed at the college. He parked there and said, "I want to see you again." So I just blurted out, "Wouldn't you like to accept Christ as your Savior?" He said, "I sure would," I told him he could do that right there in the car. So we bowed our heads in prayer. I prayed and then asked him to pray, and he accepted Christ.
Now I'll be honest with you, I would never have opened my mouth if the Lord hadn't prompted him to open up the conversation. We need to be led by the Spirit.—From Edited Messages on Acts by J. Vernon McGee
