The Solicitation to Apostasy
Deuteronomy 13 confronts Israel with three escalating scenarios of solicitation to apostasy: the false prophet, the intimate family member or friend, and the corrupt city given over to idolatry. In each case the text demands not tolerance but purging, because defection from the living and true God constitutes treason against the theocratic covenant order. The chapter's severity is inseparable from its mercy: faithful execution of justice removes the cause of divine wrath and secures the covenant blessings sworn to the fathers. The passage presses the hearer to examine whether fidelity to God holds firm against both miraculous signs that lead astray and the subtler pull of intimate relationships.
Ask FGBC #39: What Does The Bible Mean By The Unforgiveable Sin?
What is the unforgivable sin, and should a troubled conscience fear having committed it? Drawing on Matthew 12:31-32 and the apostasy warnings of Hebrews 6 and 10, this Q&A response argues that blasphemy against the Holy Spirit is not a momentary verbal offense but a wholesale, persistent rejection of the redemptive work of God in Christ — impugning the Spirit's testimony to Christ's works and glory. The defining mark of a genuine apostate is not anguish or doubt but a hardened, unrepentant contempt, like those who cried 'crucify him.' Anyone asking whether they have committed this sin gives evidence by that very asking that they have not.
The War Against the Midianites
Numbers 31 records God's command to execute vengeance upon the Midianites for their role in seducing Israel into idolatry and apostasy at Baal-peor — a crime instigated by Balaam that caused 24,000 Israelites to perish under divine judgment. The study argues that the severity of Moses' orders upon return from battle is not arbitrary cruelty but the just execution of God's judicial wrath against specific criminal offenders. Three passages from Deuteronomy (chapters 13, 20, and 21) are examined to demonstrate that Israel's normal wartime ethic was governed by humane principles that distinguished her from surrounding nations, underscoring that the Midianite war was a unique act of covenantal vengeance rather than a general template for holy war. The session closes by grounding these difficult texts in the consistency of God's justice, goodness, and faithfulness in bringing his people to the land of promise.
Ask FGBC - Dec 2024 Podcast with Pastors Butler and Porter, Batch 4
A panel of two pastors works through a batch of listener-submitted questions spanning baptism and the Lord's Supper, the eternity of hell, church membership, faith and fear, the unpardonable sin, images of Christ, dry preaching, and extra-biblical theological vocabulary. Across each topic the answers are grounded in Scripture and the 1689 London Baptist Confession, with particular attention to second-commandment concerns, the nature of saving faith, and the perseverance of the saints. Listeners are urged to anchor their assurance not in the strength of their own grip on Christ but in the immutable decree of election and the intercession of the Triune God.
The Harlotry of Israel in Moab
Numbers 25 records the final plague upon the first generation of Israel: sexual harlotry with the women of Moab leading directly to idolatrous worship of Baal of Peor, the very site where God had been blessing Israel through Balaam's compelled oracles. The chapter unfolds in three movements — the sin of the people, the zealous intercession of Phinehas, and the commanded judgment on Midian — each illuminated by the Apostle Paul's use of this passage in 1 Corinthians 10 as a warning to the new covenant church. Phinehas, acting as a priestly guardian of the sanctuary with divinely commended zeal, typifies Christ's priestly office and intercession, pointing forward to the one whose unchangeable priesthood averts the wrath of God from new covenant Israel through his life, death, and resurrection. The passage calls the church to flee idolatry, to marry only in the Lord, and to perfect holiness in the fear of God, lest spiritual harlotry — defection from the living God through unholy alliances — repeat in the new covenant community what it wrought in the old.
The Requirements for Religious Life
Numbers 15 interrupts the narrative of Israel's rebellion in chapters 11–14 with renewed covenant obligations — laws of offerings, provisions for unintentional sin, and the command to wear tassels. The placement is deliberate: faithfulness to God's ordained means of grace is the proper remedy for the kind of corporate collapse just witnessed. The sermon traces how God's judgment on one generation does not exhaust His covenant mercy, and draws a typological line from Mosaic sacrifice and priesthood through to the once-for-all offering of Christ and the believer's advocate before the Father.
The Anatomy of a Benediction
The closing verses of Hebrews unfold one of the most theologically dense benedictions in the New Testament, packed with titles, covenantal language, and christological weight. This exposition works through six elements of the apostolic blessing in Hebrews 13:20–21: the divine title 'God of peace,' the mediatorial title 'great shepherd of the sheep,' the covenantal foundation of Christ's blood, the petition for completeness in obedience, the doxology rendered to Christ, and the necessity of divine enabling for every good work. The sermon draws together the covenant of grace, the resurrection as the divine vindication of Christ's atoning work, and the believer's dependence on God's working in them both to will and to do — all to the end that glory be given to Christ forever.
The Believer's Race, Part 3
Hebrews 12:3–11 presents three reasons believers must persevere in the race of faith: the example of Christ who endured hostility from sinners, the forgotten exhortation of Proverbs 3 concerning divine discipline, and the Father's sovereign purpose in chastening every son He receives. The sermon argues that suffering and hardship are not evidence of God's absence or anger, but proof of the Father-son relationship and the means by which God conforms His people to the image of Christ. Believers are called to neither despise nor be discouraged by chastening, but to receive it as the painful yet fruit-bearing discipline of a loving Father, whose corrections are light in comparison with the sins that deserve them.
The Believer's Race
Hebrews 12:1 commands the people of God to run with endurance the race set before them — a race marked by real obstacles, both the weights that encumber and the sins that ensnare. The sermon works through the broader perseverance theme of Hebrews, identifies the duty, obstacles, and manner of the Christian race, and then turns to the cloud of witnesses of Hebrews 11 as the primary incentive: not spectators watching the runner, but testimony from Abel, Enoch, Noah, Abraham, Moses, the judges, David, and the prophets that God is faithful in every conceivable circumstance. The appeal is not to muster willpower but to look by faith at those who have gone before, hear their unified witness that God upholds his people, and so press forward in the joy and gratitude that belongs to those justified by grace through faith in Christ.
The Announcement of the Betrayal
John 13:18–30 records Jesus announcing the betrayal of Judas Iscariot in the upper room, and this exposition works through the passage in two movements: the announcement of the betrayal (vv. 18–20) and the identification of the betrayer (vv. 21–30). Three features of the announcement receive careful attention — the fulfillment of Psalm 41:9 in Christ's passion, the absolute divinity of Christ declared in the repeated 'I am' of verse 19 (grounded in Exodus 3:14), and the nature of apostolic discipleship as delegated ambassadorship. The removal of Judas from the disciple group exposes the distinction between holding church office and possessing saving grace, a distinction pressed as a question of self-examination for every hearer.
The Righteousness of David
David's declaration in 2 Samuel 22:21–25 that God rewarded him according to his righteousness stands in apparent tension with his gross sins of adultery, murder, and failure to act in the rape of Tamar. This sermon resolves that tension through the theology of justification by faith alone, demonstrating from Romans 4 that David, like Abraham, was accepted by God not on the basis of personal moral achievement but through the imputed righteousness of Christ received by faith — the same way any sinner in any covenant has ever entered the presence of God. David's own writings, particularly Psalm 32 and Psalm 51, confirm that he understood his standing before God to rest on atonement, forgiveness, and the crediting of another's righteousness, not sinless perfection. The sermon closes with a call to treasure public worship as David did, and to bring great sin to the great Savior who justifies the ungodly.
The One Thing Needful
Luke 10:38–42 presents two sisters whose contrasting postures before Christ expose a perennial danger for the people of God: the distraction of much serving to the neglect of the one thing needful. The sermon works through Martha's fourfold complaint — impugning Christ's care, demanding he redirect Mary, mingling grumbling with service, and collapsing into self-pity — before turning to Christ's gentle double-named rebuke and his commendation of Mary's humble discipleship. The passage does not condemn service, family, work, or daily necessity, but it does condemn the disordering of priorities that allows lawful things to crowd out devotion to the word of Christ. The lasting and untakeable benefit Christ promises to those who sit at his feet is the governing application: seek first the kingdom, receive the word with a noble heart, and trust that all other things will be added.
The Warning Against Apostasy
Hebrews 10:26–31 contains one of the New Testament's starkest warnings, and the question it raises is precise: who has committed the sin of willful apostasy, and can it be the believer who struggles with remaining corruption? This sermon works through the nature and judgment of apostasy, distinguishing between the sensitive saint who sorrows over indwelling sin and the apostate who openly tramples the Son of God underfoot, counts the blood of the covenant a common thing, and insults the Spirit of grace. Drawing on Calvin, Owen, Gill, and Ursinus, the sermon argues that the persons in view are not struggling believers but outright rejecters of the gospel — in the original context, Hebrew Christians who publicly renounced Christ to return to the Levitical system. The chief comfort the passage affords is precisely this: the believer who fears he has committed the unpardonable sin almost certainly has not, and is called to draw near, hold fast, and consider one another in the confidence of a once-for-all sacrifice that saves to the uttermost.
The Problem of Israel's Apostasy
Israel's apostasy in Judges 2:7–3:6 follows a pattern rooted not in ignorance but in a failure to know the Lord experientially — a failure that produced syncretism, Baal worship, and divine chastisement. The sermon traces the root, description, and divine response to Israel's apostasy, showing that God's repeated raising up of judges was not provoked by Israel's repentance but by his own covenant faithfulness and mercy. Samson is presented as a type of Christ, each of the twelve judges pointing typologically to the Savior who would definitively deliver his people from their sins. The church is exhorted to keep herself unspotted from the world, resisting the toleration that leads by degrees to full apostasy.
The Defense of the Faith
Jude 3 commands every believer — not merely pastors or theologians — to contend earnestly for the faith once for all delivered to the saints. This sermon examines the exhortation itself, the internal threat posed by sneaky, ungodly apostates who pervert grace and deny Christ, and the practical preparedness Jude prescribes: remembering apostolic warning, building up on the most holy faith through Scripture and prayer, and resting in the assurance that God himself preserves his people. The defense of the faith is not pessimistic trench-holding but confident advance grounded in Christ's promise to build his church against which the gates of Hades shall not prevail.
The New and Living Way
Hebrews 10:19–25 presents two grounds of confidence for the people of God — boldness of access to the Holy of Holies through Christ's blood and flesh, and the possession of a great high priest over the house of God — and then presses three exhortations upon that foundation: draw near, hold fast the confession of hope, and consider one another to stir up love and good works. The sermon traces the problem of sinful man's exclusion from God's presence from Exodus 40 through the Levitical sacrificial system to its resolution in the incarnation and definite atonement of Christ, who consecrated a new and living way. Particular attention is given to the prohibition against forsaking the assembly, argued to be grammatically tied to the third exhortation and theologically governing all three, so that corporate Lord's Day worship is the ordained context in which God's people draw near, are educated in hope, and mutually provoke one another to love and good works. The sermon closes by calling the unconverted to look to Christ and the converted to embrace their shared responsibility for one another's souls through faithful churchmanship.
The Deliverance of David by the Lord
The providential preservation of David under Saul's murderous pursuit, traced through 1 Samuel 19, illuminates how God delivers His people by ordinary and extraordinary means alike. Three escalating attempts on David's life — a thrown spear, messengers at his house, and a third company sent to Ramah — are each turned aside, culminating in the Spirit of God falling upon Saul's own men and upon Saul himself, rendering them incapable of violence. The chapter also traces the inverse arc of Saul's apostasy: his repeated, deliberate disobedience issues in a divine hardening that mirrors the 'giving over' of Romans 1. The central pastoral lesson is that the clearest evidence God has not deserted His servant is not that the trial is past, but that the servant is still standing in the middle of it.
David's Rise and Saul's Resentment
1 Samuel 18 traces the beginning of David's rise to prominence and Saul's corresponding descent into envious rage. The chapter presents a sustained contrast between Jonathan's covenant faithfulness — his willing deferral to David as the Lord's anointed — and Saul's increasingly vicious antagonism, from murderous spear-throwing to cynical manipulation of marriage negotiations. The sermon draws out the theological spine of the narrative: the presence of Yahweh with David is both the cause of his success and the source of Saul's terror, a pattern that points forward to the New Covenant reality that those united to Christ by faith enjoy the peace, protection, and communion of God. Listeners are called to watch against both external and internal threats to the kingdom, and to pursue the God-fearing faithfulness modelled in David rather than the self-securing apostasy of Saul.
The Victory of David Over Goliath, Part 1
1 Samuel 17:1–37 is not a psychological self-help story about facing personal obstacles; it is a narrative of the glory of God. Goliath defies the armies of the living God, and David — a type of Christ — meets that defiance not with natural courage but with faith grounded in the proven faithfulness of Yahweh. The sermon traces the contrast between Israel's faithless paralysis and David's God-centred confidence, showing that apostasy produces cowardice while faith in the living God produces boldness. The practical summons is to walk by faith rather than by sight, to serve faithfully in ordinary providential callings, and to draw confidence for present trials from remembered past mercies.
The Lord's Arrest in the Garden
Matthew 26:50–56 records the arrest of Jesus in Gethsemane, and this exposition works through four movements in the passage: Peter's misguided sword-stroke, Christ's rebuke concerning the nature of the messianic kingdom, his rhetorical indictment of the mob's hypocrisy, and the disciples' desertion. The sermon shows that Christ's surrender was entirely voluntary, governed by the covenant of redemption and the fulfillment of prophetic Scripture, not by any inability to resist. Hearers are warned against mistaking external proximity to Christ for saving grace, called to zeal tempered by theological knowledge, and directed to the Lord's Supper as an occasion to 'kiss the Son' in faith rather than in the betrayal of a Judas.
The Rejection of Saul by the Lord, Part 2
The rejection of Saul in 1 Samuel 15:24–35 exposes the anatomy of false repentance, the character of a reprobate, and the nature of a God who does not change. The sermon works through Saul's admission of guilt, Samuel's execution of Agag, and the theological tension between God's expressed regret and his immutability, resolving that tension through the doctrines of divine impassibility and anthropopathism. The justice of God in dispatching the wicked is shown to be a cause for righteous rejoicing, not moral discomfort, as texts from Judges 4–5 and Proverbs 11 confirm. Saul's downward trajectory — blame-shifting, false piety, delusion, fake repentance, and apostasy — is held up as a warning that great privilege does not equal saving grace, while Christ's imputed righteousness is offered as the only ground of true standing before God.
The Prediction of Desertion and Denial
Matthew 26:31–35 records Jesus predicting both the desertion of all His disciples and the specific denial of Peter on the night of His arrest. The passage demonstrates that the salvation accomplished at the cross was entirely the work of Christ alone — His friends fled, leaving no horizontal assistance — and that Scripture, citing Zechariah 13:7, had appointed this scattering from eternity. The sermon draws out the persistent problem of remaining corruption in the regenerate: the pride, self-confidence, and lofty self-assessment that Peter epitomizes are not unique to him but are symptomatic of all God's people. The remedy is not stronger resolution but a biblical self-assessment that drives the believer away from confidence in the flesh and toward continual dependence on the grace and Spirit of God.
The Second Missionary Journey, Part 5
Acts 17:10–15 records the ministry and departure of Paul and Silas at Berea, where the Jewish hearers were commended as 'more noble-minded' than those in Thessalonica because they received the word with readiness and examined the Scriptures daily to verify Paul's proclamation of Jesus as the Christ. The sermon expounds three movements in the text — the perseverance of the missionaries, the tenacity of unbelieving opposition, and the noble-mindedness of the Bereans — and draws sustained application from Nehemiah 8 and the parable of the sower in Luke 8 on the right reception of God's word. The Berean example is pressed as a standing model for the church: Scripture is sufficient and self-evidencing, and the truth has nothing to hide and everything to gain by investigation. Hearers are exhorted to come to the word with expectancy, attentiveness, reverence, and responsiveness, since faith comes by hearing and hearing by the word of God.
The Past as a Present Reminder
Hebrews 10:32–39 calls suffering believers to recall God's proven faithfulness in former days as the present ground for ongoing endurance. The apostle first rehearses the Hebrew Christians' early trials — public reproach, solidarity with persecuted brothers, and joyful acceptance of plundered possessions — showing that heavenly-mindedness, not stoic willpower, sustained them then and must sustain them now. He then exhorts them not to cast away their confidence, grounding Christian perseverance not in moral grit but in faith in the Son of God who loved and gave himself for his people. The sermon applies this to every believer: remember what God has done, set your hope on the enduring possession in heaven, and press forward by faith rather than drawing back to perdition.
Genesis 25:1-34
Genesis 25 records the closing of Abraham's life and the opening of Isaac's story, setting the stage for the covenant line to advance through election rather than nature or merit. The passage contrasts Ishmael's twelve princes — fulfilling God's promise to Hagar — with Isaac's barren household, where twenty years of earnest prayer precede the miraculous conception of twin sons whose prenatal struggle prefigures the enmity between Israel and Edom. The chapter culminates in the profaneness of Esau, who despises his birthright for a single meal, illustrating the danger of immediate gratification over covenant inheritance — a warning the author of Hebrews applies directly to apostasy. God's sovereignty in election, his faithfulness across generations, and the incremental advance of the covenant promise toward Christ are the governing themes throughout.
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.
The Warning Against Apostasy
Hebrews 10:26–31 is one of the most pastorally misread warning passages in the New Testament, and this expository sermon works carefully to distinguish the sin of apostasy from the ordinary, ongoing sin of weak believers. The apostate is not a struggling saint who confesses and seeks mercy; he is one who, having made an outward profession of faith, openly and obstinately repudiates Christ — trampling the Son of God underfoot, counting the blood of the covenant a common thing, and insulting the Spirit of grace. The sermon draws on Owen, Calvin, Gill, and Ursinus to establish that apostasy is a total, willful renunciation of the gospel, not any species of sin for which Christ has made atonement. Believers burdened by remaining corruption are urged to distinguish themselves from apostates by the very instinct that drives them to the throne of grace — and to make full use of the means of grace God has appointed to preserve them from the apostasy the passage warns against.
The Judgment Seat of Christ
Matthew 7:21–23 is often misread as a warning to believers to produce more good works, but the passage concerns entrance into the kingdom of heaven and exposes the damning error of self-righteousness. The false professors are condemned not because they lacked works but because they rested their hope for acceptance with God on those works rather than on Christ's blood and righteousness — a form of lawlessness that is an assault on the cross. The will of the Father in Matthew 7:21, rightly understood through John 6:28–40, is to believe on the Son whom He sent; justification is by faith alone, received once, and the Sermon on the Mount functions as law to drive sinners to the foot of the cross rather than to self-congratulation.
The Good Soldier's Incentives
What motivates a Christian to endure suffering rather than abandon the faith? Expounding 2 Timothy 2:8–13, this sermon identifies three incentives Paul sets before Timothy: the contemplation of Christ in his incarnation and resurrection, the conduct of the Apostle Paul who endured chains as a self-described evildoer for the sake of the elect, and the believer's present and future communion with Christ — dying with him, living with him, and ultimately reigning with him. The sermon closes with a sober examination of the faithful saying in verses 11–13, distinguishing the warning against apostasy from the assurance belonging to the wavering but genuine believer, and connects the Lord's Supper as a divinely appointed means of grace for sustaining the good soldier's contemplation of Christ.
The Good Soldier of Jesus Christ
Paul's commands to Timothy in 2 Timothy 2:1–7 address the inevitable reality of hardship in gospel ministry and Christian life, and the apostle equips believers to face it through three vivid analogies: the devoted soldier, the disciplined athlete, and the diligent farmer. A fourth consideration emerges from verse 7 — the dedicated disciple who both thinks seriously and depends on sovereign grace for understanding. The sermon applies these four models not only to ordained ministers but to every Christian, closing with a sustained exhortation to perseverance in the 'middle mile' of the Christian race, grounded in the 1689 London Baptist Confession's doctrine of the perseverance of the saints.
