When we pray as a family at night before the boys go to bed we all have our personal thanks and petitions to add. The boys also have a Scripture verse that they say each night. They've said these verses for maybe six years now. I think they "get" it.
Roo, "As for me and my house, we will serve the LORD. Joshua 24:15."
Boo, "I will lie down and sleep in peace, for You, O LORD, will keep me safe. Psalm 4:8."
Yup. That about covers it.
