In this moment, Jesus institutes what would become a central practice for believers: the act of communion. The cup He offers is symbolic of His blood, which would soon be shed for the forgiveness of sins. By saying, "Drink from it, all of you," He invites everyone to partake in the salvation He offers. This act of drinking from the cup signifies the believers' participation in His sacrifice. The communion table is not just for a select few, but for all who are willing to accept His gift of grace. The act of drinking from the cup reminds us that salvation is freely offered to all and that, through the blood of Christ, we are reconciled to God. Jesus gives thanks before distributing the cup, showing His gratitude for the fulfillment of God's plan through His sacrificial death. This verse emphasizes the communal aspect of the Christian faith—believers, united by faith, come together to partake of the sacrifice Christ made for them, proclaiming His death until He returns.
