Chapter 12 marks a turning point Paul's letter. He moves his conflicting church readers to the how of the unity thing; how it works to be a body (different parts, all working together, belonging to one another) and what the love that fuels this will look like (the same kind of love for your friends, our church body members, and our enemies alike!) And he begins this instruction with one of the most poignant battle cries in all of scripture: what God wants from us is for us to offer our whole selves to him, and to not fall into worldly patterns of managing our human mess, but to let Him transform us.
