Philippians 2:16-18

holding fast the word of life, so that in the day of Christ I will have reason to glory because I did not run in vain nor toil in vain. But even if I am being poured out as a drink offering upon the sacrifice and service of your faith, I rejoice and share my joy with you all. You too, I urge you, rejoice in the same way and share your joy with me.
