What we do at Communion.
To eat and drink worthily (1Cor. 11:29) at communion requires knowledge and discernment of the Lord’s body. The Lord bids us to remember Him in His death. That is to do more than rehearse the physical steps of his suffering unto death. It requires us to comprehend His mission to redeem His people, His power to deliver from sin’s guilt and His right to become King to rule over the hearts of His people. It requires that we understand his offices as prophet, priest and King. The more we grow to understand the ministry of Christ in His death, the more we will participate with discernment. The word “discernment” means to discriminate, which is to separate the right from the wrong.
Here are four things we are to renew in our hearts as we come to the communion table: WE MUST RENEW OUR REPENTANCE, TRUST, DESIRE AND THANKSGIVING [R.T.D.T.]
 Renew your repentance from the world.
Your commitment to being a Christian is to turn from following the world. You are to crucify the world and its lusts. It means:
 Renew your total trust (faith) in Christ’s redeeming work alone for acceptance with God.
Trust is the key word here. Saving faith is a hearty trust in the Saviour’s work and word (Eph. 1:7-15, 2:8).
 Renew your desire for the Holy Spirit to apply the power of redemption to our heart. Praying for the Spirit to minister:
The apostle Paul emphasised these three things:
"For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost" (Romans 14:17).
 Renew your thanksgiving to God who loved us and chose you to belong to Christ.
A keyword in communion is “eucharist” (Luke 22:19). It means thanksgiving. There is nothing mysterious in the term other than to demonstrate personal thanksgiving for Christ’s blood and sacrifice for our redemption (2 Cor. 9:15, Revelation 5:8-14).
We would deeply fail to observe the Lord’s table properly if we were not zealous in our appreciation of our Saviour’s substitutionary sufferings. He took our place and died in our stead. He bore all for us.
The surest testimony of salvation is: “Christ died for me.”
The Saviour led His disciples to sing a hymn immediately after He instituted the Lord’s Supper.
“And when they had sung an hymn, they went out into the mount of Olives” (Mark 14:26).
It is proper, then, for us to make good use of our hymnal in a communion service to sing about the blood and death of Christ.
Thank you Lord for saving my soul
Thank you Lord for making me whole
Thank you Lord for giving to me
Thy great salvation so rich and free.
