A few years back, while teaching at a Lutheran high school, we became "professional church shoppers." Over a three year period, we attended about 3 dozen churches -- most, but not all, LCMS. What we discovered is that, if you are a visitor, you are invisible. The members all talk to each other. So does the pastor. In almost every case, no one spoke to us, other than to hand us a bulletin. Some had greeters that smiled and said hello (but never "I don't believe we've met; can I help you?") I made it a point to sign the book, or the card (or whatever) -- few followed up at all; some sent a form letter; one made a phone call. If a church doesn't even bother to care about the people that make the effort to show up, what is the chance that it will care for the people in its neighborhood that need to hear about Jesus??
