1 Corinthians 15:1-7

1 Brothers and sisters, I'm making known to you the Good News which I already told you, which you received, and on which your faith is based.
2 In addition, you are saved by this Good News if you hold on to the doctrine I taught you, unless you believed it without thinking it over.
3 I passed on to you the most important points of doctrine that I had received: Christ died to take away our sins as the Scriptures predicted.
4 He was placed in a tomb. He was brought back to life on the third day as the Scriptures predicted.
5 He appeared to Cephas. Next he appeared to the twelve apostles.
6 Then he appeared to more than 500 believers at one time. (Most of these people are still living, but some have died.)
7 Next he appeared to James. Then he appeared to all the apostles.
