Yes, the Lord’s Supper should remind us of the seriousness of our sin, and our urgent need to repent and flee from from it. But for repentant sinners, the dominant note at the Lord’s Table is not fear, guilt, or condemnation. It is assurance that though we are great sinners, Christ is a greater Savior, and in him we have full forgiveness of all our sin. Dr. Ray Van Neste says it so well:
The Supper is not for those who have it all sorted out. In fact, it is for sinners only. By taking the elements we confess we are sinners in need of a Savior, and we confess again that we take Christ, with his work at the cross, as our Savior. Among the many benefits of this practice is that it keeps us from even sounding legalistic and after the rebuke of sin allows us to close on the note of sins forgiven. People deeply struggle to believe that God loves them, to receive the amazing word that in Christ all our sins are forgiven. In Communion we have the truth of Christ’s redeeming love portrayed, showing us that His forgiveness is so real we can taste it.
One of many golden selections from Ray Van Neste’s chapter, “The Lord’s Supper in the Context of the Local Church,” in The Lord’s Supper: Remembering and Proclaiming Christ Until He Comes (Nashville: B&H Academic, 2010), 389. If you want to find someone at the Lord’s Table treating sin with the utmost seriousness, and at the same time applying the soul-strengthening truth of the Gospel, this is your resource.
