What does the Bible say about the significance of the Last Supper?

The Last Supper holds profound significance as it marks the institution of the New Covenant and foreshadows the sacrificial death of Jesus, who is the true Passover Lamb. It is during this meal that Jesus shares bread and wine with His disciples, symbolizing His body and blood which He willingly sacrifices for humanity's sins. This act not only fulfills Old Testament prophecies but also establishes a new way for believers to commune with God through faith in Christ's atoning sacrifice.
