This sermon examines Hebrews 9:11-12 to demonstrate that Jesus Christ is the substance behind the Old Testament shadows, specifically identifying Him as the ‘true tabernacle’ and the ‘sanctuary’ of heaven. The exposition distinguishes between the earthly tabernacle, which prefigured the incarnation of God dwelling among His people, and the heavenly sanctuary, where Christ entered once for all to secure eternal redemption. By analyzing the Greek term for redemption, the message emphasizes that Christ’s sacrifice was a final, sufficient payment that freed believers from the slavery of sin, contrasting this biblical truth with various theological errors regarding the atonement. The sermon concludes by urging believers to move beyond spiritual shadows to the substance of Christ, finding assurance in His finished work and joy in the abiding presence of God.
