Romans 1-11 gives us a doctrinal core. Why?
Because we need to change. God teaches us so that He can tranform us. So that we can think and live and act the way God intends us to.
Truth is meant to transform us.
The information is meant for our transformation.
So read Romans 12:1 as an important hinge verse about God transforming us into who He wants us to be. Then read the rest of Romans 12 as prayer after prayer for personal transformation.
