14Do all things without murmurings and disputes, 15that you may become blameless and harmless, children of God without blemish in the midst of a crooked and perverse generation, among whom you are seen as lights in the world, 16holding up the word of life; that I may have something to boast in the day of Christ, that I didn`t run in vain nor labor in vain.
