1 Corinthians 15:3-11

For I passed on to you as of first importance what I also received, that Christ died for our sins according to [that which] the Scriptures [foretold], [Is 53:5-12] and that He was buried, and that He was [bodily] raised on the third day according to [that which] the Scriptures [foretold], [Ps 16:9, 10] and that He appeared to Cephas (Peter), then to the Twelve. After that He appeared to more than five hundred brothers and sisters at one time, the majority of whom are still alive, but some have fallen asleep [in death]. Then He was seen by James, then by all the apostles, and last of all, as to one untimely (prematurely, traumatically) born, He appeared to me also. [Acts 9:1-9] For I am the least [worthy] of the apostles, and not fit to be called an apostle, because I [at one time] fiercely oppressed and violently persecuted the church of God. But by the [remarkable] grace of God I am what I am, and His grace toward me was not without effect. In fact, I worked harder than all of the apostles, though it was not I, but the grace of God [His unmerited favor and blessing which was] with me. So whether it was I or they, this is what we preach, and this is what you believed and trusted in and relied on with confidence.
