Be pure and blameless before Jehovah

"Do all things without murmurings and disputings 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 holding forth the word of life; that i may rejoice in the day of Christ, that not run in vain, neither laboured in vain."
