The bread of the Last Supper is the body, while the wine of the Last Supper represents the crucifixion. Wine represents the blood that is shed on the cross, but the blood also represents Grace that is provided by the crucifixion.
Luke 22:20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Wine and blood represent the new covenant or new testament, and it is a fulfillment of the promise made to Abraham. The blood of Christ redeems the children of God and makes them worthy to enter the kingdom of God.
Genesis 4:2 And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.
The story of Cain and Abel is the story of the fall of humanity. Cain was a farmer whose labor produced bread. Abel was a keeper of sheep, and his sacrifice would involve the shedding of blood. Cain (the bread or the body) kills Abel (the blood or the redemption). Cain is exiled from the kingdom. After the fall of humanity, we have no redemption, and we are no longer worthy to enter the kingdom of God.
There is also the story of Joseph which parallels the story of Jesus.
Genesis 40:20-23 And it came to pass the third day, which was Pharaoh’s birthday, that he made a feast unto all his servants: and he lifted up the head of the chief butler and of the chief baker among his servants. And he restored the chief butler unto his butlership again; and he gave the cup into Pharaoh’s hand: But he hanged the chief baker: as Joseph had interpreted to them. Yet did not the chief butler remember Joseph, but forgat him.
In the story of Joseph there was a baker (the body), and a butler or cup bearer which is the wine. The wine represents the blood, which is the crucifixion or the redemption. These two prisoners were in the prison with Joseph, and Joseph interpreted a dream for both of them. Joseph interpreted their dreams to mean that the cup bearer would be restored to the palace, but the baker would be killed.
The baker (bread or body) is killed, but the cup bearer (blood, crucifixion or redemption) is restored to the palace. It is often said that this story is referring to Christ. His body (the baker) is killed, and He (the cup bearer) ascends to Heaven.
The baker (body) is killed on the third day. The body of Christ was not killed on the third day. It was on the third day that Christ was resurrected from the dead. Joseph represents Christ, while the baker and the cup bearer represent us. The baker is our body, and the cup bearer is our spirit which is redeemed.
On the third day Jesus was resurrected, and it is by His crucifixion and resurrection that our spirit is separated from our flesh. The flesh (baker) dies, while the spirit (cup bearer) is restored to the palace. This refers to us.
Mark 15:27 And with him they crucify two thieves; the one on his right hand, and the other on his left.
Luke 23:42-43 And he said unto Jesus, Lord, remember me when thou comest into thy kingdom. And Jesus said unto him, Verily I say unto thee, Today shalt thou be with me in paradise.
At the cross Jesus is both the body and the blood. It is His body that is laid down, and His blood that is shed. The two thieves, like the two prisoners, represent us. Like the two prisoners, one represents our body and the other represents our spirit. They are both thieves because the body and spirit are one person, and in their complete unity they are both guilty. Christ is between the two thieves, and this represents how He justifies the separation of the spirit from the flesh.
Joseph (Jesus) asked the cup bearer (us) to remember him, but the cup bearer forgot all about Joseph. The good thieve (our spirit) asked Jesus to remember him, and Jesus said, “today shalt thou be with me in paradise”.
Jesus remembers us, but we forget Jesus.
Years later when the cup bearer remembered Joseph, Joseph was put in charge, and he saved the kingdom from famine.
We should remember Jesus.
