My daughter asked a terrific question during our Bible reading last night. She wanted to know why the pronouns had changed from "they" to "we" in Acts 16. We talked about the fact that Luke wrote the book of Acts. The kids were able to realize that the transition from "they went and did things" to "we went and did more things" meant that Luke had joined Paul's group. My daughter also wanted to know why Luke didn't just say that he began travelling with Paul.
I was very proud of my daughter for noticing this very minor change. It not only showed that she was paying attention, but also lets me know that she is already equipped to handle the first step of studying the Bible for herself- the step of observing what the text actually says.
