“I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship” (v1). Paul tells believers that being “a living sacrifice” means that, as our minds are renewed and we know God more (v2), we understand how to function as His people. Instead of envying others or seeking our own glory (v13), we use our gifts – prophecy, serving, encouragement, teaching, leadership, etc – for the whole Body’s benefit.
“Do not be conformed to this world” (v2). The world says that we live in competition with each other, but God says we are a Body, with Christ as our head, and we need one another.
