1 Corinthians 11:25-26

And Jesus did something like that at the end of the dinner too. He picked up a cup of wine and said, “Drink from this cup. God has agreed to save people, and I will die so he can do that. My blood will come out, and it is like I’m using my blood to sign God’s new agreement with people, to say that they are not guilty of the bad things they did. So every time you have this special dinner and drink from this cup, remember that my blood came out, and that I died for you.” That’s what Jesus said that night. You see, every time you eat that damper and drink from that cup you are saying that Jesus died for you. And you will keep on doing that until he comes back again.
