Philippians 2:13-16

for it is God who worketh in you both to will and to work, for his good pleasure. Do all things without murmurings and questionings: that ye may become blameless and harmless, children of God without blemish in the midst of a crooked and perverse generation, among whom ye are seen as lights in the world, holding forth the word of life; that I may have whereof to glory in the day of Christ, that I did not run in vain neither labor in vain.
