The Followers of the Lamb
Revelation 14:1–13 presents ten characteristics of those who belong to Christ, set against the backdrop of the unholy trinity's assault on the church in Revelation 12–13. Working from a preterist hermeneutic, this exposition argues that the 144,000 on Mount Zion represent the fullness of the Jewish-Christian church — sealed, worshipping, spiritually chaste, redeemed by blood, truth-speaking, and blameless before God by imputed righteousness. The sermon insists that these characteristics are indicative, not imperative — describing what is true of every believer in union with Christ — and closes with a call to rest in the Word rather than feelings, trusting Christ alone as the ground of standing before God.
The Passion, the Resurrection, and Justification by Faith Alone
Romans 4:25 sets the death and resurrection of Jesus Christ as the inseparable ground of the believer's justification before God. This sermon expounds that single verse within the broader context of Romans 3:21–4:25, where Paul establishes that justification is by faith alone — not by circumcision, moral refinement, or works — and demonstrates from Abraham and David that God imputes righteousness to the ungodly who believe. The necessity of Christ's atoning death and bodily resurrection are treated as twin non-negotiables: without blood shed there is no remission, and without a risen Savior justification remains unconfirmed and faith is vain. Believers are called to rest in the finished work of Christ alone — delivered up for their offenses, raised for their justification — and to resist the accuser by returning to these objective gospel realities.
The Need for Biblical Mindedness
Colossians 3:1–4 grounds every practical exhortation in the chapter — about marriage, work, and social relations — in a prior command: set your mind on things above. This sermon argues that Christianity is fundamentally a religion of knowledge, that the image of God in man is expressed chiefly through rational thought, and that biblical mindedness is the necessary foundation for worship, sanctification, and faithful witness. The command to seek heavenly things is rooted in three theological realities — the believer's past death with Christ, present hiddenness in Christ, and future appearing with Christ in glory — and is pursued not through legalism, mysticism, or asceticism, but through prayerful study of Scripture.
The Command to Walk in Christ
Colossians 2:6–7 presents what Paul considers the heart and substance of the entire epistle: a command to walk in Christ, grounded entirely in the prior reception of Christ by faith. This sermon works through three particulars of that command — the indicative basis (what God has already accomplished in salvation), the imperative itself (walking in Him), and the attendant circumstances (being rooted, built up, established in the faith, and abounding in thanksgiving). The believer's walk is not a self-generated moral effort but a response to sovereign grace, sustained by the same divine power that accomplished the initial rooting in Christ.
The Church at Thyatira
Revelation 2:18–29 records the longest of the seven letters to the churches of Asia Minor, addressed to the smallest city — Thyatira. Christ presents himself to this church as the Son of God with eyes like flame and feet like burnished bronze: omniscient judge and certain executioner of his threats. The church is commended for real growth in works, love, service, faith, and patient endurance, yet condemned for tolerating a false prophetess called Jezebel who seduced believers into sexual immorality and idol-food — the precise sins forbidden by the Jerusalem Council. The letter closes with a call to hold fast until Christ comes and a promise that overcomers will share in his royal rule over the nations, receiving Christ himself as the Morning Star.
The Great Commission
Matthew 28:18–20, the Great Commission, grounds the church's evangelistic and discipleship mandate not in human strategy but in the universal authority of the enthroned Christ. The sermon traces three interlocking realities: the authority behind the commission (Christ's sovereign rule over all things), the activity the commission requires (making, baptizing, and teaching disciples), and the active agent who sustains it (Christ himself present with his people to the end of the age). Believers' baptism is expounded as a visible sign of union with Christ, remission of sins, and public covenant commitment — an ordinance reserved for disciples, not infants — and the entire commission is set within a robustly Calvinist framework in which God alone adds to his church by sovereign grace.
One, Holy, Catholic, Apostolic Church
The four classical attributes of the church — one, holy, catholic, and apostolic — are not ecclesiastical slogans but biblical realities grounded in the redemptive work of Christ. Drawing from John 10:14–16 and John 17:15–23, this sermon argues that each attribute finds its source in Christ alone: his atoning blood purchases a universal people, his sanctifying work makes the church holy, his intercession secures her unity, and his apostles' doctrine defines her apostolicity. The sermon closes with a direct call to repentance for those outside of Christ and a summons to every believer to walk worthily of these gospel-given realities.
The Foundation for Christian Baptism
Baptism is grounded not in the merit or decision of the one being baptized, but in the death and resurrection of Jesus Christ, who was himself 'baptized' — overwhelmed unto death — as a substitute for sinners. The sermon works through Mark 10:32–45 to show that Christ's language of drinking the cup and being baptized with his baptism refers to his substitutionary suffering at Calvary, not his water baptism by John. Baptism is therefore an act of obedience that publicly declares the believer's identification with the triune God and union with Christ in his death, burial, and resurrection, while picturing — though not providing — the forgiveness of sins.
