In Matthew 18:10, Jesus says:
"See that you do not despise one of these little ones. For I tell you that their angels in heaven always see the face of my Father in heaven."
Here is what I think. I think that when big folks hurt little folks just because they can, there are Much Bigger Folks who will, sooner or later, exact justice. Maybe in this life, certainly in the next. Repent ye therefore and believe. You've been warned.
