Philippians 2:14-15

14Whatever you are doing, do not complain. And do not argue.

15Then you will not be guilty of anything that is wrong. You will be clean inside yourselves. You will be living in a completely good way, as God's children should. In this world, you are living among bad people who have turned away from what is good. But you must bring light into this dark place, like stars that shine in the night.
