As Paul sits in prison for the gospel, his chains are a constant reminder that he is not simply a prisoner of Rome but sees himself as a prisoner for the Lord. He is bound to Christ, his Church, and to the community of believers he is writing to. Paul implores this community to “make every effort to keep the unity” (4:3) of Christ. As the Church today, when we choose to fight, not for what divides but for what unites us, we become a community that reflects the presence, power and purpose of Jesus to the world around us. The unity that we are called to maintain is not a creation of the Church, but flows from our identity in Christ (2:13–22). Unity was so important to Jesus that he prays that we would be one so that the world would know of the love of God (John 17:21–23).
