Mark 14:22-25 (ESV Strong's)
22 And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, “Take; this is my body.” 23 And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. 24 And he said to them, “This is my blood of the covenant, which is poured out for many. 25 Truly, I say to you, I will not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God.”
Jesus shares with us in the fruit of the new covenant when we drink from the cup of communion. The kingdom of God is on earth in the body of Christ. This is our first cup of the wedding feast to come in which the bride of Christ will receive the full inheritance that is ours as His children.
He is with us in the communion of the new covenant in the kingdom in our hearts.
The last supper before the cross has become the feast of never ending life in Christ. His body has become ours and we bear the fruit of His Holy Spirit.
