The Appearance of Christ to the Disciples
John 20:19–23 presents two interlocking realities: the presence of the risen Christ among His fearful disciples on the first day of the week, and the commission He gives them to carry His gospel into the world. The peace Christ pronounces is not a generic greeting but the fruit of His atoning wounds — the satisfaction of divine justice that reconciles guilty sinners to God. From this the sermon argues that the church's entire mission is delimited by Christ's own sending: not entertainment, social uplift, or political activism, but the proclamation of the forgiveness of sins through the crucified and risen Lord, empowered by the promised Holy Spirit.
Ask FGBC #19: Should Christians engage in politics?
Should Christians engage in politics? This Q&A addresses the Christian's dual citizenship — as a member of both the church and the civil body politic — and argues that while political engagement is neither commanded nor forbidden by Scripture, it is entirely lawful. The discussion distinguishes the church's spiritual sword (the gospel and the keys of the kingdom) from the civil state's coercive sword, drawing on the Noahic covenant in Genesis 9 as the foundational charter for justice, family, and enterprise in society. The threefold use of the law is applied to show why preaching against abortion or civil injustice is ethics and theology, not partisan politics.
The Authority of the Church
Christ's promise in Matthew 16:19 to give 'the keys of the kingdom of heaven' to the church raises two perennial dangers: authoritarian abuse of ecclesiastical power and the outright abdication of it. This sermon expounds the identity of those entrusted with these keys (apostles, elders, and the gathered congregation together), the nature of the authority delegated (binding and loosing through preaching and discipline), and the proper ground of confidence when the church acts — not sacerdotal infallibility, but the assurance that heaven ratifies the church's faithful obedience to Scripture. The practical conclusion is that the keys are exercised through the proclamation of the Word, the admission and exclusion of members, and the administration of the sacraments — never through entertainment, self-help, or moral do-goodery.
The Penalty for Blasphemy
Leviticus 24 addresses both the daily obligations of tabernacle worship and the capital penalty for blasphemy, grounding each in the direct speech of God to Moses. The chapter's narrative pivot — an incident in which a man of mixed Israelite and Egyptian descent blasphemes the name of Yahweh — becomes the occasion for case-law application of the third commandment, surrounded by reminders of the lex talionis and the equal accountability of stranger and native-born alike. The typological furniture of the holy place (lampstand and showbread) points forward to Christ as the true light and bread of life, while the blasphemy legislation, with its witness requirements and retributive principle, reveals a God who guards his own honour and structures justice with both severity and safeguard. The sermon exhorts hearers to put away every profane use of the divine name and to cultivate a reverent, wholehearted employment of it in thought, word, and worship.
The Condemnation of the Religious Leaders, Part 1
Matthew 23:13 introduces the first of eight woes Christ pronounces upon the scribes and Pharisees — men who, rather than opening the kingdom of heaven, slammed its door in the faces of those seeking entrance. The sermon establishes the prophetic precedent for Christ's condemnation by tracing the woe-oracle tradition through Isaiah and Habakkuk, and by grounding Christ's authority in the Deuteronomy 18 promise of the coming prophet. The first woe is shown to encapsulate all the rest: the religious leaders shut out others through hypocrisy, legalism, doctrinal heresy, and above all their rejection of Jesus as the Messiah. The sermon closes with a direct call to believe the gospel — to look to Christ and live, as Israel once looked to the bronze serpent in the wilderness.
2LCF Chapter 26 - Of the Church, Part 12
Church discipline is not the invention of elders or ecclesiastical tradition but the revealed mind of Christ, set forth in Matthew 18:15-17 and grounded in the covenantal logic of church membership. This session of a confession study on 2LCF Chapter 26 walks through the escalating steps of discipline — private confrontation, the introduction of witnesses, and the appeal to the whole church — demonstrating that each step is designed for the recovery of the offender, not his destruction. The session concludes by addressing the implications of the final step of excommunication: what it means to treat a man as a heathen and tax collector, whether he may still attend worship, and how the confession itself provides redress when church authority is abused.
2LCF Chapter 26 - Of the Church, Part 12
Church membership is not an optional preference for believers but a biblical obligation that makes church discipline both possible and meaningful. This exposition of 2LCF 26.12 establishes church membership as the prerequisite to all formal discipline, then works through Matthew 18:15 to show how private confrontation — grounded in Leviticus 19:17 and shaped by love, humility, and a commitment to God's law rather than personal preference — is the first and foundational step in recovering an offending brother. The sermon closes with practical counsel on the disposition required of both the offended and the offender, calling every church member to deal faithfully with sin rather than avoiding, broadcasting, or bitterly nursing it.
The Possession of the Church's Authority
Christ's declaration in Matthew 18:18 — 'whatever you bind on earth will be bound in heaven' — establishes that the local church possesses a real, though delegated, authority to exercise the keys of the kingdom through gospel preaching and church discipline. Drawing on the parallel passage in Matthew 16:19 and the Heidelberg Catechism's definition of the keys, the sermon argues that binding and loosing refer to the church's authority to exclude the unrepentant and restore the repentant, always in accordance with God's word and never by arbitrary preference. Verses 19 and 20 ground this authority in the corporate prayer and the promised presence of Christ himself among his people when they faithfully implement these keys. The sermon closes with a summons to love the church, exercise its authority prayerfully, and pursue its three primary duties — preaching, discipline, and the administration of the sacraments — without addition or subtraction.
The Procedure for Church Discipline, Part 3
Church discipline in Matthew 18:15–17 follows a divinely ordered three-step procedure: private confrontation, the involvement of witnesses, and finally the public action of the gathered church. This sermon works through the second and third steps, examining the Old Testament warrant for the two-or-three-witness requirement (Deuteronomy 19:15) and the nature of the church's decisive judgment to treat the unrepentant as a heathen and tax collector. The goal at every stage remains the recovery of the sinning brother, and excommunication — a corporate act of the whole congregation, not merely the elders — is understood as an expression of love and a means God may use to bring a rebel to repentance. The sermon closes with an evangelistic warning: the church's earthly excommunication is a pale shadow of the final excommunication pronounced by Christ on the last day.
The Procedure for Church Discipline, Part 2
Church discipline is not optional for any believer — Matthew 18:15 commands the offended party to go directly and privately to the one who has sinned against them, before any witnesses or congregational involvement. This sermon works through the situation, command, and outcome of that first private confrontation, distinguishing between genuine sin and mere preference, and between the path of direct rebuke and the path of love covering a multitude of sins. The goal throughout is not excommunication or the infliction of pain, but the recovery of a sinning brother and the preservation of the purity and peace of Christ's church.
The Procedure for Church Discipline, Part 1
Matthew 18:15 introduces Christ's binding procedure for church discipline within the local church — a subject that exposes both the authority of the head of the church and the love that drives the restoration of erring brothers. Four introductory matters are addressed before the first step is reached: the definition of formative and corrective discipline, the necessity of discipline as obedience to Christ, key presuppositions (including five biblical arguments for defined church membership), and the practice considered against common misreadings of Matthew 7 and Matthew 13. The purpose of discipline is shown to be threefold: the reconciliation and restoration of the offender, the purity of Christ's church for the glory of God, and the protection of the people of God from the spread of unchecked sin.
The Authority of the Church
Christ's declaration in Matthew 16:19–20 invests the church with delegated authority — expressed through the metaphor of keys — to bind and to loose in the kingdom of heaven. This authority is not absolute and belongs to no single officer; it is entrusted to the church as a whole to be exercised through the faithful preaching of the gospel and the discipline of the membership. The sermon works through three observations: identifying the stewards of this authority, the nature of the authority delegated, and the specific functions of binding and loosing. The congregation is called to prize Christ's church, exercise her God-given authority through the Word alone, and testify freely that Jesus is the Christ, the Son of the living God.
