The covenant of the Lord is forever!

The Lord's Supper is not simply a picture of a situation that occurred before the death of the Lord Jesus Christ; it goes far beyond that. The Lord established this supper so that we would forever remember what he has won for us.
26 And as they were eating, Jesus took bread, and when he had given thanks, he broke it, and gave it to his disciples, and said, "Take, eat; this is my body." 27 And he took the cup, and when he had given thanks, he gave it to them, saying, "Drink from it, all of you; 28 for this is my blood of the new covenant, which is shed for many for the forgiveness of sins. 29 And I say to you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in my Father's kingdom."
Matthew 26:26-30
