Philippians 2:
14 Do all things without murmurings and disputings:
15 That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;
16 Holding forth the word of life; that I may rejoice in the day of Christ, that I have not run in vain, neither laboured in vain.
17 Yea, and if I be offered upon the sacrifice and service of your faith, I joy, and rejoice with you all.
18 For the same cause also do ye joy, and rejoice with me.
Phi.2:14-18
