The idea that we must have a a formal program or predetermined approach to sharing the Gospel is more a mystery to me than how God saves anyone. Sharing the Gospel is living it! Yes, at times it involves preaching but other times?
I remember a meeting I had many years ago when I met a single mom and her little girl while I was stationed at Adak, Alaska. Anyway, as I watched the toddler, the mom told me that she wasn’t married. Although I hadn’t met her, she apparently knew I was a Christian. Still, all I said to her was that the little girl was beautiful. About six months later, I received a letter from the mom. Apparently God had used that simple response, ‘she’s beautiful’ to draw her to Himself. She expected to be judged; at least, that’s where her conviction kept her In bondage at that time, and she expected to hear me say something else. Anyway, she had become a part of a fellowship in Anchorage and was prospering in the Lord.
Consider too what we learn from the disciple Nathaniel (John 1:48-49), who proclaimed Jesus as the Son of God. Why? What had He said? Nothing, really. Jesus merely said He had seen Him afar under a fig tree!
Yes, I’d say that the Gospel can be shared as much by a smile as a sermon; and I think God can work a smile and a simple look as a marvelous introduction to His Son and the greatest thing of all? We didn’t even know that we had communicated God’s eternal gift! I wouldn’t have known had it not happened the Lord led the mom to write me… well, not until I found out in heaven. Either way, it’s to His glory. The point is, we don’t know how God has prepared the hearts of those He calls, and while God might work through a program, it’s a matter of our heart and how it is we come to smile.
