What is "the measure of faith that God has assigned" (Romans 12:3)? What is the gift of "exhortation"? What are spiritual gifts and how do they function? Romans 12 depicts the body of Messiah in all its diversity, and calls upon us to commit ourselves to the body, offering ourselves as "living sacrifices" to the Almighty.
For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another. (Romans 12:4-5)
