Mark 14:22-25.
The Passover meal was highly significant in the life of God's people. It was also the perfect time and place for Jesus to institute the Lord's Supper. Full of meaning, depth, and breadth, the Lord's Supper is a rich convergence of the Scriptures. But when it all boils down in the end, the Lord's Supper serves as a simple reminder that Jesus has paid it all.
