Luke 22:19-20 HCSB
And He took bread, gave thanks, broke it, gave it to them, and said, “This is My body, which is given for you. Do this in remembrance of Me.” In the same way He also took the cup after supper and said, “This cup is the new covenant established by My blood; it is shed for you.
This cup is the symbol of the new agreement between you and God that has been set in motion by Jesus.
In God’s word, the cup is mentioned many times, usually referring to God’s wrath.
Matthew 26:39 HCSB
Going a little farther, He fell facedown and prayed, “My Father! If it is possible, let this cup pass from Me. Yet not as I will, but as You will.”
Jesus wasn’t afraid of the religious leaders or the Romans. He wasn’t afraid of Satan or of demon possessed people. He wasn’t afraid of storms. But He trembled when faced with the cup of God’s wrath.
What was in that cup? The Bible says God placed on Jesus the iniquity, the wickedness, the sin of us all. That cup was full of shame, suffering, wickedness, and separation from God. Jesus drank that cup all night and the next day, as he was mocked, beaten, and crucified. When the last portion had been taken, He said “It is finished.” The cup was empty.
THE CUP IS EMPTY.
The cup of sin and shame, of pain and suffering, is empty. It was given to Jesus instead of us.
There is another cup. It is full of His blessing. When we take communion together, the wine and bread are the symbols of an exchange of cups between God and ourselves – our cup of wrath for His cup of blessing. The only thing that could overcome death was the life Jesus brought.
1 Corinthians 11:25-26 HCSB
In the same way, after supper He also took the cup and said, “This cup is the new covenant established by My blood. Do this, as often as you drink it, in remembrance of Me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes.
