Philippians 2:15-18

that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world, holding fast the word of life, so that I may rejoice in the day of Christ that I have not run in vain or labored in vain. Yes, and if I am being poured out as a drink offering on the sacrifice and service of your faith, I am glad and rejoice with you all. For the same reason you also be glad and rejoice with me.
