In Ephesians chapter 4, Paul turns his attention to the matter of unity within the body of Christ as he exhorts us to walk in a manner worthy of our calling in Christ (verse 1).  The first half of the chapter provides a vivid portrayal of the type of unity that should characterize the functioning of the church: Spirit-led, interdependent co-laboring of diversely gifted yet deeply integrated, mature followers of Jesus Christ.
