Lights in the World

12Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling, 13for it is God who works in you, both to will and to work for his good pleasure.

14Do all things without grumbling or questioning, 15that 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, 16holding 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.

Emphasis mine.
