Philippians 2:14-18

Do all things without murmurings and questionings: that ye may become blameless and harmless, children of God without blemish in the midst of a crooked and perverse generation, among whom ye are seen as lights in the world, holding forth the word of life; that I may have whereof to glory in the day of Christ, that I did not run in vain neither labor in vain. Yea, and if I am offered upon the sacrifice and service of your faith, I joy, and rejoice with you all: and in the same manner do ye also joy, and rejoice with me.
