The Last Supper occurred during Passover in Jerusalem, when the city's population would dramatically increase from 50,000 to over 200,000 people. Jesus meticulously planned this final meal, sending Peter and John on a discrete mission to prepare the location, using specific signs to maintain secrecy from those who sought to arrest Him. During this traditional Passover celebration, Jesus revolutionized the meaning of the meal's elements, establishing a new covenant with profound implications for humanity's relationship with God. The unleavened bread and wine took on new significance as symbols of His body and blood, representing the ultimate sacrifice that was to come. This transformation marked a fundamental shift from a law-based religious system to one centered on faith and direct relationship with God. The new covenant established at the Last Supper offers complete forgiveness of sins, inner transformation through the Holy Spirit, and a direct connection with God that wasn't possible under the old system. This pivotal moment in history continues to shape Christian practice and understanding of God's redemptive plan.
