God's grace toward me was not in vain
Letters of Paul to the Corinthians | 1Cor 15 1-10
The Resurrection of Christ
15 Now I would remind you, brethren, in what terms I preached to you the gospel, which you received, in which you stand, 2 by which you are saved, if you hold it fast—unless you believed in vain.
3 For I delivered to you as of first importance what I also received, that Christ died for our sins in accordance with the scriptures, 4 that he was buried, that he was raised on the third day in accordance with the scriptures, 5 and that he appeared to Cephas, then to the twelve. 6 Then he appeared to more than five hundred brethren at one time, most of whom are still alive, though some have fallen asleep. 7 Then he appeared to James, then to all the apostles. 8 Last of all, as to one untimely born, he appeared also to me. 9 For I am the least of the apostles, unfit to be called an apostle, because I persecuted the church of God. 10 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.
