5th grader: Is all scripture true?
Me: Yes, it was inspired by God for our salvation, though it may be hard to understand at times.
5th Grader: But, it says here at the end of the bible, "I warn everyone who hears the prophetic words in this book: if anyone adds to them, God will add to him the plagues described in this book." So, does that mean, if I write at the end of that page, "By [insert name here]," does that mean God will kill me?
Me: Probably. That's what God says.
5th: Oh.... wide eyed, he immediately puts the book back on the shelf and gets very quiet
I hope I didn't scare him too badly.
