The sermon centers on the theological significance of the tabernacle in Exodus 25 as a divine foreshadowing of the incarnation, where God's promise to dwell among His people finds its fulfillment in Jesus Christ. It emphasizes that the tabernacle, though outwardly unimpressive, symbolized the hidden glory of God, which was fully revealed in the incarnate Word—Jesus, who dwelt among humanity as both fully divine and fully human. The sermon defends the hypostatic union—the doctrine that Christ is one person with two natures—against historical heresies such as Ebionism, Gnosticism, and Nestorianism, affirming that Jesus' true humanity and deity are essential for His role as Savior and High Priest. Drawing from Scripture, especially Philippians 2, Hebrews, and John's Gospel, it underscores that Christ's incarnation was not a mere appearance but a real, historical event involving a genuine human nature, yet without sin, secured by the virgin birth and upheld by the Chalcedonian Definition. Ultimately, the tabernacle's purpose—to house God's presence—finds its eternal realization in Christ, who is Immanuel, God with us, and whose glory is the ultimate revelation of divine grace and redemptive love.
