1. TO COMMEMORATE
Jesus said, “Do this in remembrance of me” (1 Cor. 11:24,25). He was intentional to choose Passover to establish the Lord’s Supper (Matt. 26:17). Passover was a celebration to remind his people of their deliverance from Egypt. Whereas, the Lord’s Supper is a celebration of the deliverance from sin for those who trust in Jesus. (Matt. 26:28).
The bread and the cup remind us of Jesus' sacrifice on the cross. We participate to remember what He did for us.
2. TO ANTICIPATE
Jesus anticipated a reunion with His disciples in His Father’s kingdom, Jesus states in Matthew. 26:29 “I will not drink from this fruit of the vine from now on until that day when I drink it new with you in my Father’s kingdom” Likewise, He instructed them to partake the Lord’s Supper. "For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.” 1 Cor. 11:26
We look forward to that time when we will celebrate with Him at His great banquet table (see Matt. 22:1-14; Rev. 19:6-9).
3. TO UNIFY
Participating in the the Lord’s Supper is to participate in a congregational act by which we corporately affirm our faith. We celebrate the completed work of Christ, focusing on our unity, and visibly proclaiming to the world that Jesus is the only way of salvation.
In 1 Corinthians . 11:17-18,20,33-34, the celebration that was supposed to unify the church actually brought disunity to the church. Paul repeated “come together” five times in that passage.
We express unity by participating together in the Lord’s Supper,
