Proverbs 22:2 Rich and poor have this in common: The Lord is the Maker of them all.
No matter how you try to split the world up; be in by race, colour, creed, location, sex, whatever... God is our maker!
He created each one of us and so we are all His children in one way or another.
We have the choice as to whether we accept this and ask Him to be our Father, or ignore it and try do things by ourselves in this corrupt world!
