I’m preaching this week on Mark 14:22-26, where Jesus institutes the Lord’s Supper. I found David Garland’s comments insightful and challenging.
When the Lord’s Supper is served at the end of a worship service, people may examine their watches more than their hearts and may be worried more about dinner than how they have betrayed Jesus in the previous week or how they might betray him in the next. Mark’s account of the Last Supper [Mark 14:22-26] should jolt us awake. Each should contemplate his or her own life and confess all the ways, big and small, that he or she has betrayed the Lord and acknowledge such weaknesses. We should all be humbly aware that if one of the Twelve could betray Jesus, every Christian has that potential. This idea of self-examination, as opposed to cross-examination, is preserved in Paul’s comments on the Lord’s Supper (1 Corinthians 11:27-29), along with the idea of eating worthily. We are worthy of the Lord’s Supper when we recognize how unworthy we are. We feel its power when we also recognize that Jesus died for us and accepts us in spite of our unworthiness.
