The Ratification of the Old Covenant
Exodus 24:1–8 records the ratification of the Old Covenant at Sinai through blood sacrifice, a mediator, and the sworn fidelity of the people — all of which anticipate and are surpassed by the New Covenant inaugurated in the blood of the Lord Jesus Christ. The Old Covenant is identified not as an administration of the covenant of grace but as a covenant of works, in which Israel's standing depended upon their own obedience: 'all that the Lord has commanded we will do.' The New Covenant contrasts sharply: Christ, the true Israel of God, fulfills every covenantal obligation in the place of his people, so that the ground of the believer's standing before God is not their performance but his finished work. The sermon closes with a practical call to live at the foot of Calvary rather than at the foot of Sinai, resisting the legal temptation to ground either justification or sanctification in personal obedience.
The Crucifixion of Jesus, Part 3
Matthew 27:45–46 records the darkest three hours of history and the lone saying of Christ that Matthew preserves from the cross: 'My God, my God, why have you forsaken me?' This sermon works through the cry of dereliction with careful attention to what the text does and does not teach, ruling out any ontological division within the Trinity, any dissolution of the hypostatic union, and any notion that all three persons suffered at Calvary. The forsakenness Christ voiced was real — a qualified withdrawal of the Father's consolatory smile and favour, not an abandonment of love — because Christ stood as the covenant surety of his people, bearing the punishment of loss that sinners deserve. The gospel comfort that follows is decisive: because Christ cried 'Why have you forsaken me?' those united to him by faith will never have to.
The Role of the Law in Justification
Romans 3:20 stands at the hinge of Paul's argument in Romans 1–3: the universal condemnation of Jew and Gentile is summarized and confirmed, and the ground is cleared for the proclamation of a righteousness that comes apart from the law. This sermon examines both the unlawful use of the law — seeking justification before God through law-keeping, which Paul categorically condemns — and the lawful pedagogical use, by which the law defines sin, demonstrates the gravity of human guilt, and drives the sinner to Christ. The central burden is that no amount of moral effort can secure acceptance with God, because the problem lies not in the law but in the sinner; the law's only saving function is to press men toward the law-keeper, Christ, whose obedience and sacrifice are the sole ground of justification.
