Steve W. gave a great analogy on Sunday morning.
Do not be conformed to the patterns of this world but be transformed by the renewing of your mind (Romans 12:2).
He mentioned he's discovered many things about babies in the past three years, one being that babies need to be upside down, head first, to be born. If the head comes out, the rest of the body will follow.
It's the same with the renewing of your mind. The patterns of this world are things like jealousy, pride, consumerism, and the list goes on and on… If you get your head/mind out of the patterns of this world, the rest of your life will follow.
