Philippians 2

14 Do everything without complaining and arguing, 15 so that no one can criticize you. Live clean, innocent lives as children of God, shining like bright lights in a world full of crooked and perverse people. 16 Hold firmly to the word of life; then, on the day of Christ’s return, I will be proud that I did not run the race in vain and that my work was not useless.
