Activity, Scavenger hunt: Have the family gather a toy sword or something similar, a compass, and a copy of the Book of Mormon for each person before reading these verses. Give everyone 5 minutes max to find these items.
Make family scripture time productive. Get the kids excited. If kids can see how the Book of Mormon applies to them and if reading the Book is FUN, you might hear, "Is it time to read yet?", rather than, "Do we have to?" We are counseled to SEARCH the scriptures, not just read them. It takes preparation to do that with children. This is the preparation that I've done. Now I have it for reference next time. And you do too. Comments welcome.
