1 Corinthians 15:10-11

10But God was very kind to me. He helped me to become a different person. And because God has been so kind to me, the result has been great. I have worked more than all the other apostles. But it was not really I myself who could do that work. No, I could do it because God was so kind to me.

11So then, all of us apostles teach the same good news about Christ. That is the message that you have believed. It does not matter which of us told it to you, whether it was me or someone else.
