Philippians 2:14–16
14 Do all things without grumbling or disputing, 15 that you may be blameless and innocent, children of God without blemish in the midst of a crooked and twisted generation, among whom you shine as lights in the world, 16 holding fast to the word of life, so that in the day of Christ I may be proud that I did not run in vain or labor in vain.
