23 And whatsoever ye do, do it heartily, as to the Lord, and not unto men;
24 Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ.
I must work the works of him that sent me, while it is day: the night cometh, when no man can work.
58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
