When Jesus told His disciples to eat and drink in “remembrance of Me,” He wanted them to think especially of Him in body to death. His flesh and blood were the means by which God’s wrath was absorbed against our sin. The cross was a reckoning, a settling of accounts so that God could be both just and the justifier of those who believe in Christ. That makes the communion table a table of reckoning, a sign of Christ’s atoning substitute for all who would ever believe.
When we eat the bread and drink the cup we reckon that it’s true; Jesus died and rose again. When we come to this table we also reckon that it’s true for us. We died with Christ and have been raised in Him.
We know that our old self was crucified with Him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin….Now if we have died with Christ, we believe that we will also live with Him. We know that Christ being raised from the dead will never die again. (Romans 6:6, 8-9)
We believe the truth of the gospel account, and then we believe the truth that we died and rose again in Him.
So you also must consider yourselves dead to sin and alive to God in Christ Jesus. (Romans 6:11)
The translation “consider” could be “count” (NIV) or “reckon” (KJV). This is a table of reckoning. As you hold the bread and wine, hold to the reality by faith. We partake of the signs of God reckoning with sin on Christ, and as we partake we reckon that our union with Christ matters for everything.
