Engaging Confessional Baptists on Covenant Theology (Part 1): Typology

Review of Fred Sanders, Fountain of Salvation: Trinity and Soteriology

Fred Sanders is likely the best-known name in recent theology concerning the doctrine of the Trinity and rightly so. He has addressed the topic at the academic and popular levels, providing hermeneutical advancements and introductory treatments.1 His most recent book, Fountain of . . . Continue reading →

Parachurch or Pastoring (Part 2)

Previously began a discussion about parachurch ministries in relation to the church. The point was to raise a concern about how, frequently, parachurch ministries implicitly, if (perhaps) unintentionally, try to usurp the visible, institutional church’s primary role in God’s plan to save . . .

Parachurch Or Pastoring? (Part 1)

The church has a mission and purpose, received directly from Christ’s appointment. Despite her imperfections, Scripture does not seem to suggest that Jesus thought the church would need support from further external organizations. Rather, the Bible indicates that the church would perform . . . Continue reading →

Review: Estelle, The Primary Mission Of The Church (Mentor, 2022)

Western culture is ripping apart, to varying degrees depending on the country, over issues of social justice and cultural welfare. That increasing pressure has also often included the advocates of various social causes demanding assent from everyone else. This no exception approach to ideological uniformity has also often affected the church, as proponents of cultural issues impose their views upon us as another institution that must get in line with secular orthodoxy. Continue reading →

Postmodern Confessionalism?

The relationship between biblical authority and ecclesiology has always been interesting. The Reformed commitment to sola Scriptura was never biblicism, as if it were solo Scriptura.1 The Reformed tradition from its outset was at the same time devoted to the Bible’s ultimate . . .

A Pastor’s Public Persona

In many ways, the pastor lives his life in front of his people. Apart from mega-church pastors who might choose to isolate themselves from the people they shepherd (which notably does not apply across the board to every pastor of a large . . . Continue reading →

Bond And A Betrayal Culture

There are two problematic layers built into No Time to Die’s manipulative betrayal of Bond fans. The first, and arguably less substantive, is the film’s abandonment of the 007 formula. Movie critics have praised the decision to depart from the standard format of find the villain, defeat the villain, get the girl, get away with a dryly humorous quip. This praise, however, is precisely what reveals the elitist nature of the modern entertainment industry. There is a necessary question: If twenty-five movies (plus the novels and a few video games) have had immense commercial success for sixty years while abiding by the same formula, what suggests that the audience wants the films to depart from the formula? Quite obviously, it seems that we continue to pay money to watch Bond movies because we want the formula. If we wanted something else, we would see a different movie. Continue reading →

An Aberration Or Standard In Progressive Covenantalism? Issues About Covenant Conditions

Caneday’s main argument is to undermine the law-gospel distinction. In his words, “This chapter disavows the notion that all of Scripture consists of two isolatable messages: law, consisting of God’s demands, and gospel, composed of God’s gracious giving. Instead, it argues that the formulation of covenant stipulations remain the same while the content of stipulations changes.” (pg. 103; italics original). Continue reading →

Review: Grant Macaskill, Autism and the Church: Bible, Theology, and Community (Waco, TX: Baylor University Press, 2019)

Since first being credentialed by a presbytery in 2014, several topics have occupied my thoughts for extended periods of time regarding how best to preach and to pastor people wrestling with difficult issues, but none so much as the matter of mental . . . Continue reading →

John Piper, Future Grace: The Purifying Power of the Promises of God, rev. ed. (New York: Multnomah, 2012)—A Thorough Review

Pastor John Piper is well-known for his role in sparking the “young, restless, and Reformed” movement, mainly through his emphases on God’s sovereignty and serious expository preaching. There are no doubt numerous present members of Reformed churches who ended up there because of initial investigations of Reformed theology that began with hearing or reading John Piper. Personally, Piper was my first exposure to a thorough and biblical explanation of predestination in some of the appendices of the 2003 edition of Desiring God, which I was told to read shortly after becoming serious about my faith.

Kingdom Through Covenant—Round Two

Kingdom Through Covenant is a massive work of biblical theology written from a Baptistic perspective, now in its second edition.1 My very first attempt at public writing was a review of KTC’s first edition, which I did while in seminary, and which Dr. Clark very graciously posted on The Heidelblog. With more experience, I have often looked back with acute awareness of that review’s weaknesses and wished I could redo it. I am thankful for the chance to review the second edition on the same platform with hopes to improve my comments and assessment concerning this work. Continue reading →

Do Not Insist on Your Own Way

Recently, I have been reading Carl Trueman’s excellent newest book, The Rise and Triumph of the Modern Self (Crossway, 2020), and listening to Christianity Today’s fascinating podcast about Mark Driscoll’s ministry, The Rise and Fall of Mars Hill. One thing that stood out to me, which I think captures an ongoing pastoral issue throughout the church, is the predominance of preferences. Continue reading →
