There are a lot of people who know Jesus as Savior and Lord, and perhaps know the concept of God and Father, but the practice that they have put on display is something other than the likeness of the image. The image that they have may be a concept that was given to them by a man-made religious system that does really what I'm doing here today, and that is to tell you about who God is.
Lessons about God can only inform us, but revelations by His Holy Spirit transform us and change us from the inside out.
The Bible doesn't say be conformed to the world, it says don't be conformed to the world, but be transformed by the renewing of your mind. There's a transformation, a metamorphosis that God wants to take us into, and it happens when our thought processes change.
