So, I saw our little neighbor-guy riding his bike on Saturday. He asked me when church was, and I said, “Classes are at 10, and worship at 11.” I was a little taken aback when he said, “No…what day is Church?”
Wow, are we conditioned to Christendom or what? I told him that we always meet on Sunday, and that we were looking forward to seeing him there. He wasn’t there yesterday, so I’m going to stop by and make sure his grandma knows that he was very well-behaved (curiosity is not misbehavior!) and is welcome anytime.

Wow. We are way too entrenched in our own subculture when we assume everyone knows how it operates. I’m right there with you.
