What's a Living Sacrifice To Do?

After exhorting the Romans to be a living sacrifice to God, transformed by the renewing of their minds, Paul then describes what a living sacrifice is transformed to do. The Christian Presenting himself as a Holy, Living, Sacrifice to God is to give Proactive, Humble, Loving Service to God's People (in the local church). And this service is to be done in Humility (3-8), Love (9-16), and Peace (17-21).
