The Promise of the Covenant of Grace
Galatians 3:15–18 presents Paul's covenantal argument that the Mosaic law, given 430 years after the Abrahamic promise, cannot annul the covenant of grace nor supplement faith with legal works as the ground of justification. The sermon traces four interlocking points: the immutability of God's redemptive promise, the nature of Abraham's faith in Christ as the singular promised seed, the pedagogical and temporary character of the Mosaic covenant as a distinct covenant of works, and the inheritance as freely given by promise rather than earned by law. The pastoral application is a call to rest entirely on Christ, the champion of the covenant of grace, and to resist every system that adds law-keeping or circumcision to faith as the basis of standing before God.
Spurgeon & Open Air Preaching
Drawing on Hebrews 13:7's command to remember and follow faithful ministers, this lecture examines the life, preaching, and open-air ministry of Charles Haddon Spurgeon as a model for gospel proclamation. The speaker presents material from his published doctoral dissertation on Spurgeon's open-air preaching, working through three open-air sermons and Spurgeon's own pedagogy for street evangelism. A recurring application presses the listener — whatever their theological sophistication — to proclaim the excellencies of Christ to all people, including the lowest and most despised.
The Oracles of Balaam, Part 1
Numbers 23 records the first two oracles of Balaam, in which God sovereignly overturns Balak's hired curse and compels a pagan seer to pronounce blessing upon Israel instead. The first oracle establishes the singularity of the covenant people — a nation dwelling apart, not reckoned among the nations — and the impossibility of cursing those whom God has not cursed. The second oracle grounds that protection in the immutability of God: because God is not a man that he should lie or repent of his word, no sorcery or divination can prevail against Jacob. The passage ultimately anticipates Romans 8:31 — if God is for his people, no Balak, no Balaam, and no adversary can stand against them.
God the Righteous Judge
Psalm 94 presents God as the righteous judge who hears the cry of His oppressed people, sees the wickedness of their persecutors, and will not ultimately abandon His inheritance. This expository treatment works through the chiastic structure of the psalm, showing how the cry for justice (vv. 1–3) is answered by justice administered (vv. 20–23), and how the folly of those who deny God's omniscience mirrors the divinely-given wisdom of His people. The sermon draws out the covenant comfort of God's chesed — His steadfast faithfulness to those He has chosen — as the ground of peace in the midst of affliction, and closes with a direct call to repentance for any who remain outside of Christ.
The New and Living Way
Hebrews 10:19–25 presents two encouragements and three exhortations for the covenant people of God. The two encouragements — bold access into the holy of holies by the blood of Jesus, and the possession of a great high priest — ground the three commands that follow: draw near with a true heart in full assurance of faith, hold fast the confession of hope without wavering, and consider one another so as to stir up love and good works. Neglect of these exhortations is the path by which professing believers drift toward the apostasy warned against in verses 26–31, making faithful corporate worship, steadfast confession, and mutual encouragement indispensable means of perseverance.
False Repentance and the Immutable God
The final section of 1 Samuel 15 (verses 24–35) exposes the anatomy of false repentance through the self-serving confession of King Saul, who admits sin while still deflecting blame and soliciting public honour. The study contrasts Saul's hollow words with David's unqualified confession in 2 Samuel 12, showing that genuine repentance owns sin without excuse, is directed Godward rather than reputation-ward, and issues in changed conduct rather than mercenary requests. Samuel's unyielding fidelity to the divine word sets the standard for prophetic and pastoral ministry. The chapter closes with the comfort of divine immutability: the God who tears the kingdom from Saul is the God who cannot lie or relent, and that unchangeableness is the believer's firm foundation.
A Call to Repentance
Malachi 3:6–12 confronts the people of Israel with a specific act of covenant faithlessness — the withholding of tithes and offerings — and calls them to return to God. The sermon works through four observations: the immutability of God as the ground of Israel's survival, the persistent mutability and apostasy of man, the call to repentance as the divinely appointed means of restored fellowship, and the remedy God himself prescribes in verses 10–12. The prosperity-gospel misreading of the 'windows of heaven' promise is firmly rejected: the promise is covenantal and corporate, not a mechanism for individual economic gain. The sermon closes by grounding all giving and all repentance in the finished work of Christ, whose self-sacrifice alone saves.
