After the meal, Jesus took a cup of wine in his hands and said, “This is my blood, and with it God makes his new agreement with you. Drink this and remember me.”
After the meal he took another cup of wine in his hands. Then he said, “This is my blood. It is poured out for you, and with it God makes his new agreement.
When we drink from the cup that we ask God to bless, isn't that sharing in the blood of Christ? When we eat the bread that we break, isn't that sharing in the body of Christ?
The people were stubborn, and something still keeps them from seeing the truth when the Law is read. Only Christ can take away the covering that keeps them from seeing.
He makes us worthy to be the servants of his new agreement that comes from the Holy Spirit and not from a written Law. After all, the Law brings death, but the Spirit brings life.
God gives peace, and he raised our Lord Jesus Christ from death. Now Jesus is like a Great Shepherd whose blood was used to make God's eternal agreement with his flock.
