My 8yo son and my 6yo daughter are currently reading I Samuel 18 - 31. A hefty reading given their age but I've asked them to take turns reading the chapters. They started during school today and got to chapter 22 before they had had enough reading. So I let them do other things, have dinner, go to karate etc. and now are back to reading for about an hour before bed. They have just finished chapter 24 and are debating what this reading is all about.
Totally unprompted Biblical debate between an 8yo and a 6yo. You can't get much better than that. Happy Mommy heart moment. :)
