This sermon explores three biblical covenants—Priestly (Numbers 25:10-13), Davidic (2 Samuel 7:8-16), and New (Jeremiah 31:31-34)—as part of God’s plan to reveal Himself and restore humanity, building on the Noahic, Abrahamic, and Mosaic covenants discussed previously. It emphasizes Phineas’s zeal for securing a perpetual priesthood, David’s line promising an eternal kingdom, and the New Covenant’s fulfillment in Jesus Christ, who permanently addresses sin. These covenants, rooted in God’s faithfulness, point to Jesus as the ultimate priest and king, urging believers to watch, wait, and witness while trusting in God’s eternal plan, commemorated through the Lord’s Supper.
