T. Austin-Sparks emphasizes the significance of the Lord's Table as a representation of companionship with Christ, contrasting it with the rejection of Judas and Israel. He explores the Passover's meaning, highlighting God's judgment against Egypt's gods and the importance of the blood as a sign of loyalty and protection for God's companions. The sermon illustrates the transition from the old Israel to the new spiritual Israel, where the Lord's Supper symbolizes a blood covenant and betrothal between Christ and His Church. Sparks calls for a recognition of the sacredness of the Lord's Table, urging believers to understand their identity as companions of Christ, set apart from the world. Ultimately, he encourages a commitment to uphold this covenant and the significance of the blood in their relationship with God.
