Communion declares Christ's finished work!
Jesus has reached the last evening. He will share with His beloved Disciples, His plan is to celebrate Passover and transform it into a special memorial to the FINISHED WORK of His death. Communion is for His church to celebrate until He Returns.
So on Christ's last evening with His beloved disciples He inaugurates the Lord's Supper as the fulfillment of all Passovers. Christ's Work of Salvation is celebrated as FINISHED!
In the midst of the supper He says in Mark 14:24 "And He said to them, "This is My blood of the new covenant, which is shed for many."
What is the New Testament or Covenant in His Blood?
Look at His words in Acts 26:18
"to open their eyes, in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins and an inheritance among those who are sanctified by faith in Me."
How does God forgive us when we are all guilty and deserving of punishment? Jesus gave Himself for us, and when He did so He FINISHED all that needed to be done to pay for sins!
