The Vainglorious Quest, The Virtuous Path, and The Veracious Contemplation
Jeremiah 9:23–24 issues a threefold structure: a prohibitive warning against glorying in wisdom, might, or riches; a prescriptive call to glory in the understanding and knowledge of God; and a veracious contemplation of who God is and what He does. The sermon situates these commands within their covenantal context — the inevitable Babylonian judgment upon covenant-breaking Israel under the curses of Deuteronomy 28 — demonstrating that wisdom, strength, and riches will not avail in the face of irreversible divine justice. True glorying is exclusively God's due, and the knowledge of the one living and true God — Father, Son, and Holy Spirit — is the only wisdom, strength, and riches that profit eternally. Hearers are called to cast off vainglory, grow earnestly in the knowledge of God, and trust in Christ alone, in whom are found all true wisdom, strength, and riches.
The Vainglory, the Virtue, and the Verity (Part 2)
Jeremiah 9:23–24 sets a prohibitive warning against glorying in wisdom, strength, and riches, and answers it with a positive prescription: glory exclusively in the understanding and knowledge of God. This sermon (Part 2) works through the 'virtue' and the 'verity' of that text — the virtue being the necessity of knowing God (as the source of all true wisdom, everlasting life, and proper humility), and the verity being the three attendant truths God announces about himself: he alone is the Lord, he exercises loving-kindness, and he governs in judgment and righteousness. The sermon closes with a direct call to those outside of Christ to abandon vainglorious boasting and close with the one in whom true wisdom, strength, and riches are found.
The Vainglory, the Virtue, and the Verity (Part 1)
Jeremiah 9:23–24 is frequently torn from its covenantal context and reduced to a generic self-improvement maxim, but the prophet issues this warning in the shadow of irreversible divine judgment upon apostate Israel. The passage divides into three movements — the vainglory of misplaced boasting, the virtue of knowing God, and the verities of his character — and this first installment works through the vainglory of glorying in wisdom, might, and riches. The sermon argues that such boasting is doubly condemned: these gifts originate with God alone and therefore belong to his glory, and they are powerless before the whirlwind of infinite divine justice that no political, military, or economic resource can deflect. The application presses both the unconverted and the indifferent to abandon every refuge in creaturely confidence and flee to Christ, the only one in whom boasting is lawful.
The New Covenant
Jeremiah 31:31–34 contains the Old Testament's sole explicit use of the phrase 'new covenant,' and this sermon expounds its announcement, essential features, and fulfillment in Christ. Against the backdrop of Judah's covenant-breaking idolatry, God promises a covenant that is unbreakable, one that internalizes his moral law, grants saving knowledge of himself, and secures the definitive forgiveness of sin. The Hebrews quotation of Jeremiah 31 and Christ's own words at the Last Supper confirm that this covenant finds its ratification in the blood of Jesus, the surety and mediator of a better covenant. The sermon closes by drawing out the Reformed Baptist implication that new covenant membership — marked uniformly by regeneration, law-internalization, knowledge of God, and forgiveness — necessarily implies believers' baptism, and by calling the unconverted to seek that fountain open for sin and uncleanness.
Vain Glory, True Glory, and the Glory of the Cross
Jeremiah 9:23–24 sets a divine exhortation against three forms of vainglory — glorying in wisdom, might, and riches — within a context of covenant judgment falling on Judah at the approach of Babylon. The sermon works through each prohibition in turn, applies them to contemporary forms of self-trust (including a proud Calvinism), and then unfolds the threefold character of the God in whom alone glory is rightly placed: his lovingkindness, his judgment, and his righteousness. All three divine perfections converge at the cross of Christ, where loving-kindness, penal judgment, and righteousness are displayed together, so that any legitimate boasting must finally be a boasting in the crucified and risen Redeemer.
The New Covenant
Jeremiah 31:31–34 announces a new covenant that surpasses every prior administration of the covenant of grace — Adamic, Noahic, Abrahamic, Mosaic, and Davidic — by guaranteeing what none of them could: an inviolable covenant secured not by human fidelity but by the covenant head, the Lord Jesus Christ. Four defining features mark the new covenant as genuinely new: the inviolability of its bond, the internalization of God's law upon the heart, the saving knowledge of God granted to every member, and the full and permanent forgiveness of sins. Against Federal Vision teaching, the sermon insists that new covenant membership is coextensive with salvation — those who fall away demonstrate they were never true members. Entry into this covenant is by grace alone, through faith alone, in Christ alone, who ratifies it in his own blood as the surety of a better covenant.
Of Pigheadedness, Babylonians, and Covenant Enforcement
Jeremiah 6 presents Yahweh's announcement of the Babylonian invasion of Judah as an act of righteous covenant enforcement — not political misfortune, but the outworking of the curses sworn in Leviticus 26 and Deuteronomy 28 against a people who had broken covenant. The sermon traces Judah's obstinate refusal to be instructed: their ears were uncircumcised, they suppressed the truth in unrighteousness, and their false prophets declared peace where there was none. Against this backdrop of divine justice and human pigheadedness, the sermon points to the necessity of sovereign grace and the new covenant promise of a Lord of righteousness who would come to accomplish what Judah could not — the redemption of guilty sinners through substitutionary sacrifice.
