Philippians 2:15-18
Then you will shine among them like stars in the sky as you hold firmly to the word of life. And then I will be able to boast on the day of Christ that I did not run or labor in vain. But even if I am being poured out like a drink offering on the sacrifice and service coming from your faith, I am glad and rejoice with all of you.  So you too should be glad and rejoice with me.
