14 Be ever on your guard against a grudging and contentious spirit,
15 so that you may always prove yourselves to be blameless and spotless–irreproachable children of God in the midst of a crooked and perverse generation, among whom you are seen as heavenly lights in the world,
16 holding out to them a Message of Life. It will then be my glory on the day of Christ that I did not run my race in vain nor toil in vain.
