And whatsoever ye do, do it heartily, as to the Lord, and not unto men;

Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ.

For it is God which worketh in you both to will and to do of his good pleasure.

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 I have not run in vain, neither laboured in vain.

Yea, and if I be offered upon the sacrifice and service of your faith, I joy, and rejoice with you all.
