We have all read the verses about unity, but it is amazing what God does when we act on it. I think God is really calling the church to put aside it's differences and unify. Each part does it's own work.
I know in my own area it has been amazing seeing what God can do when 2 or more different churches get together to try to put feet to Unity. This is the only way for a culture shift.

Ephesians 4:1-16
