Remember that witnessing is telling about the person and work of Jesus Christ not about your Lutheran Church or the things you stand for. That is all secondary. Imagine Jesus in the room and you're talking about church and he wants you to talk about him. He wants you to get people to quit thinking about all of the details and just think about Jesus and his word of promise. I am a church leader and a very well-known representative of my church and I'm very proud of my church, but that's not worth two cents when needing to save a soul or encourage someone in their faith.
