Remember how in school, the new kid used to get picked on?
Sometimes we don't like to think that God loves the downtrodden. We've got our act together, what's wrong with those "others?" If God wants them in the family? Who are we to say otherwise. Probably God knows something about that person that we're missing. Fortunately, God can override our small-mindedness and bring that person "into the family."
I don't necessarily want to bring the kitten into my "cat family," but he sure is cute and somewhat irresistible. He has gotten comfortable too, even cozying up in the hood of my jacket.
