Then I said, I have labored in vain, I have spent my strength for nothing, and in vain: yet surely my due justice is with the LORD, and my recompense with my God.
Therefore, my beloved brethren, be steadfast, unmovable, always abounding in the work of the Lord, since you know that your labor is not in vain in the Lord.
And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them who were of reputation, lest by any means I should run, or had run, in vain.
