"Mommy...Why is there an angel sitting on my shoulder? And WHY IS HE ALWAYS WATCHING ME?!" *concerned, knitted brow expression*
I assured him that yes, God does tell us in the Bible that we each have a guardian angel, but that angel isn't a double agent acting as God's spy to tell on us when we do things wrong. Our guardian angel is a good guy. And we don't know whether or not he actually sits on our shoulder. That's a bit of a spiritual urban legend, I think.
"Mommy...God is the shepherd, and we are the sheep." *big, wide eyes*
They are such precious little sponges, aren't they?
