Therefore, we also give thanks to God without ceasing: because, that when you had received of us the word of the hearing of God, you received it not as the word of men, but (as it is indeed) the word of God, who worketh in you that have believed.
Therefore, my beloved brethren, be ye steadfast and unmoveable; always abounding in the work of the Lord, knowing that your labour is not in vain in the Lord.
For this cause also, I, forbearing no longer, sent to know your faith: lest perhaps he that tempteth should have tempted you, and our labour should be made vain.
And I went up according to revelation; and communicated to them the gospel, which I preach among the Gentiles, but apart to them who seemed to be some thing: lest perhaps I should run, or had run in vain.
But by the grace of God, I am what I am; and his grace in me hath not been void, but I have laboured more abundantly than all they: yet not I, but the grace of God with me.
And I said: I have laboured in vain, I have spent my strength without cause and in vain. Therefore my judgment is with the Lord, and my work with my God.
When he shall come to be glorified in his saints, and to be made wonderful in all them who have believed; because our testimony was believed upon you in that day.
