And because of this we thank God without ceasing, because, having received the word of God heard from us, ye received not the word of men, but as it truly is, the word of God, which also is at work in you who believe.
Therefore, my beloved brothers, become ye steadfast, unmovable, always abounding in the work of the Lord, knowing that your labor is not empty in Lord.
Because of this, I too, no longer covering over it, sent in order to know your faith, lest somehow he who tempts was tempting you, and our labor became in vain.
And I went up according to revelation, and I declared to them the good-news that I preach among the Gentiles, but privately to those who were of repute, lest somehow I might be running or ran in vain.
But by the grace of God I am what I am. And his grace for me did not become empty, but I labored more abundantly than them all, yet not I, but the grace of God with me.
But I said, I have labored in vain. I have spent my strength for nothing and vanity. Yet surely the justice [due] to me is with LORD, and my recompense with my God.
when he comes to be glorified in his sanctified, and to be marveled in that day by all those who believe (because our testimony among you was believed).
