For this cause, when I could no longer endure, I also sent to know your faith, lest by some means the tempter may have tempted you and our labor may have been in vain.
And I went up by revelation. And I put before them the gospel which I proclaim in the nations, but privately to those seeming to be pillars, lest I run, or I ran, into vanity.
So that, my beloved brothers, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not without fruit in the Lord.
Then I said, I have labored in vain; I have spent My strength for nothing, and in vain; yet surely My judgment is with Jehovah, and My work with My God.
