Stephen's Defense, Part 2
Stephen's defense before the Sanhedrin in Acts 7:2–8 turns on a redemptive-historical reading of Abraham that dismantles the charges of blasphemy against the law and the temple. The sermon traces three movements: the call of Abraham (vv. 1–4), the promise of land and descendants made to a childless man (vv. 5–7), and the covenant of circumcision (v. 8). Central to the exposition is the argument that God appeared to Abraham outside the land and apart from any temple, that both circumcision and temple find their terminus in Christ, and that Abraham's justification was by faith alone — his obedience being the fruit, never the ground, of that faith. Listeners are urged to trust not in any outward religious token but in the God of Abraham who sent his Son to fulfill every covenantal obligation his people could not meet.
Free Grace Baptist Church - October 2, 2016 PM
Genesis 15 records God's covenant with Abram, and this sermon expounds that passage under two headings: the promise to Abram (vv. 1–6) and his request for a sign (vv. 7–17). The central argument is that when God alone passes between the divided animals — taking the covenant's self-maledictory oath entirely upon himself — he typifies what Christ accomplished on the cross: bearing the curse that covenant-breaking sinners deserved. Justification is by faith alone, as Genesis 15:6 declares and as Paul confirms in Romans 4 and Galatians 3; Abram's faith was not in a nebulous future hope but in the promised seed, the Lord Jesus Christ. The sermon closes by leading the congregation into the Lord's Supper, calling believers to eat and drink in grateful remembrance of the substitute who passed through judgment in their place.
The Betrayal and Arrest of Jesus
John 18:1–11 records the betrayal and arrest of Jesus, yet John's Gospel frames the scene not primarily as a display of suffering but as a revelation of divine glory. The great I AM steps forward to meet his captors, causes a detachment of soldiers to fall to the ground by the mere utterance of his name, and willingly drinks the cup of God's wrath — not as a victim, but as the covenant mediator and surety who executes the eternal decree of the Father. The sermon calls hearers to resist a narcissistic reading of the passion narratives and instead to bow in worship before the obedient Son of God, whose vicarious, substitutionary death is the sole ground of the sinner's justification.
Deuteronomy 28
Deuteronomy 28 sets out the covenantal sanctions of the Mosaic economy: comprehensive blessing for obedience and devastating curse for disobedience, with the curses dwarfing the blessings in scope and detail. The chapter's structure mirrors ancient Near Eastern treaty form, and its predictive detail concerning plague, exile, siege, and national reversal has been dismissed by naturalistic interpreters who deny Mosaic authorship — a denial the sermon firmly rejects. The curses, including cannibalism during siege and the reversal of every Abrahamic promise, are traced through Israel's history from the wilderness to A.D. 70. The sermon closes by directing the hearer to praise God for the new covenant, in which Christ as covenant surety rendered the personal, entire, exact, and perpetual obedience Israel never could, bearing the curse of the law so that the blessing of Abraham might come upon His people.
The Covenant Ceremony with Abraham
Genesis 15 records a covenant ceremony between God and Abram that is strange to modern readers yet central to understanding the entire architecture of redemptive history. God answers Abram's request for assurance by commanding him to prepare slaughtered animals, then passes between the pieces alone — a unilateral self-maledictory oath binding himself to the fulfillment of his covenant promises. The sermon argues that this solitary divine passage is ultimately fulfilled at Calvary, where Christ, as the surety and mediator of the covenant of grace, bore the curse of the covenant in the place of his elect people — which is precisely what Galatians 3:13 declares. Believers find their assurance not in their own covenant-keeping but in the oath and promise of God sealed in the blood of Jesus Christ.
A Tale of Two Covenants
Israel's repeated pledge at Sinai — 'all the words which the Lord has said we will do' — was broken almost immediately, exposing the fundamental weakness of the old covenant: its dependence on the faithfulness of sinful human parties. The new covenant does not repeat that weakness, because its covenant head is the Lord Jesus Christ, who as the second Adam pledged fidelity to the Father and executed every obligation perfectly, obediently, and completely. This sermon, preached in the context of the Lord's Supper, traces the contrast from Exodus 24 through Jeremiah 31, Matthew 26, and John 17 to show that justification rests entirely on Christ's active and passive obedience imputed to believers by faith alone. The application is a call to rest in the finished work of Christ rather than any mixture of personal faithfulness, and to come to the communion table with that covenant framework in view.
The Riches of Christ
2 Corinthians 8:9 situates a mundane financial appeal within a profound Christological argument: because Christ voluntarily exchanged the riches of his pre-incarnate glory for the poverty of humiliation and crucifixion, his people have been made spiritually rich beyond measure. The sermon traces three movements — the pre-incarnate riches of Christ, the depths of his humiliation, and the spiritual blessings he secures for his people — drawing on parallel passages in Philippians 2, Ephesians 1, and 1 Corinthians 1 and 30. The application presses believers to reckon daily with their possession of imputed righteousness, sanctification, and redemption as the only sufficient motive for generous, gospel-driven obedience.
