"Do everything without grumbling or arguing, so that you may become blameless and pure, children of God without fault in a warped and crooked generation. Then you will shine among them like stars in the sky as you hold firmly to the word of life." — Philippians 2:14-15 (New Testament)
"Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen." — Ephesians 4:29 (New Testament)
"I am not saying this because I am in need, for I have learned to be content whatever the circumstances. I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. I can do all this through him who gives me strength." — Philippians 4:11-13 (New Testament)
