Observing the Lord’s Supper softens the hearts for all those with faith. For those without faith, their participation will harden their hearts more. They eat and drink judgment on themselves (see 1 Corinthians 11:27-28). “Examine yourselves, to see whether you are in the faith.” (2 Corinthians 13:5)
Believers in Christ meet with God over a meal He’s provided. We commune with the Father and the Son by the Spirit. We fellowship in God’s presence, we fellowship with the Triune God. It is His presence that softens our hearts more than anything else.
At this Table, the Lord is proclaimed by the Word and pictured in the sacrament. We remember the gospel Word by which we are being saved: the Lord’s death for our sins in accordance with the Scriptures, His burial, and resurrection on the third day (1 Corinthians 15:1-4). We also eat and drink His body and blood. As we do, He melts our hearts by His gospel, His grace, His love, His sacrifice, His promises, His own self given for us.
The weekly feast helps our hearts. It deals with our hardening hearts by establishing peaceful thanks. In dark and stormy weeks, He comes to us in a sign of His presence, a sign of His joyful sacrifice on the cross for us. He invites all who hunger for Him to keep feeding on Him, all who trust Him to keep trusting Him. “Take heart; it is I. Do not be afraid.”
