Working on a project:
"Jacob, I need Daddy's square. Do you know what that is?"
"Yeah. It's a triangle."
(Pretty good for a 5-year-old to know what a carpenter's square is!)
"Jacob, what are you thankful for?"
"My family. My warm house. And our mighty God!"
Trying to calm him down at 2 AM after a bad dream:
"God's taking care of you while you sleep. Can God see everything?"
"Does God know everything? Does He know what you dream about?"
"Can God do anything?"
