We come to the first imperative in Philippians with Paul moving from how the gospel informs his life, to how it should inform our lives as worthy citizens of God's kingdom. This kingdom living involves standing united as believers to the outside world and standing united inside the church to guard against selfishness and pride that hurt the church's witness. The basis for this unity and harmony comes from the Triune God who first loved and served us in our sin. Thus, we must keep the person and work of Jesus ever before us to maintain our Christian unity and harmony.
