But I said, “I have labored in vain, I have spent my strength for nothing and vanity; yet surely my right is with the Lord, and my recompense with my God.”
But by the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God which is with me.
I went up by revelation; and I laid before them (but privately before those who were of repute) the gospel which I preach among the Gentiles, lest somehow I should be running or had run in vain.
And we also thank God constantly for this, that when you received the word of God which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
For this reason, when I could bear it no longer, I sent that I might know your faith, for fear that somehow the tempter had tempted you and that our labor would be in vain.
