As I've grown older, one of the best tools I've found to help in sharing the gospel is the ability to listen without making a judgment. It's not easy when error and sin are so blatantly exposed. Timing makes all the difference. There have been times when I waited for months to share the Lord to clerks at grocery stores. My approach is usually to look at their badge and to speak something regarding their names. If it says "Cathy", I might say, "So, what's that short for, Katherine?" She might nod or say something about it, maybe tell me it was her grandmother's name. "Gee," I'd reply, "so few parents name their kids those simple names these days." The next time I stop by, I might say, "Hi Katherine." She'll smile because I remembered her name. Then, I might say, "Maybe one day you'll become another Katherine Hepburn. She was a great actress. Too bad so many of the old actors are now passed on. Do you remember Pat O'Brien? I loved his Father Flanagan role in Boy's Town." And from there, a door to talk about things spiritual has opened. I might ask if she's Catholic, and we'd go from there. Witnessing has been a rewarding pasttime for me.
