What does it mean to believe in the present work of the Holy Spirit while affirming that the apostolic sign gifts have ceased?

In this episode of the Unashamed Truth Podcast, Grant Castleberry welcomes back Ryan Denton for a conversation on the Holy Spirit, historic Reformed cessationism, and the dangers of both charismatic excess and “hypercessationism.”

Grant and Ryan discuss the Spirit’s work in regeneration, sanctification, prayer, preaching, and the life of the church, while also considering dreams, impressions, providential promptings, and extraordinary experiences throughout church history. Drawing from Scripture and voices such as John Flavel, John Knox, Charles Spurgeon, and Martyn Lloyd-Jones, they ask how Christians can remain open to the Spirit’s work without compromising the sufficiency and final authority of Scripture.

This episode offers a thoughtful Reformed approach to experiencing the work of the Holy Spirit while remaining firmly anchored in the Word of God.

What calls a person to preach the gospel or carry it to the nations? And how can the church help prepare them?

In this episode of the Unashamed Truth podcast, Grant Castleberry sits down with Ian Hamilton to discuss his conversion in Glasgow, his call to pastoral ministry, and the vital role of the local church in discerning and confirming that call. Drawing on decades as a pastor and seminary professor, Hamilton explains why theological training must shape a minister’s character as well as his mind.

The conversation then turns to world missions. Hamilton shares how missionary biographies and his work with Radius International have deepened his concern for unreached peoples. His central appeal is to see the glory of Christ: the Savior is worthy of being known, loved, and worshiped among all nations.

Whether you are considering ministry or seeking to strengthen your church’s commitment to missions, this conversation offers biblical counsel and encouragement.

In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with Andy Young, pastor of Oxford Presbyterian Church in Oxford, England, to discuss reaching and discipling a new generation of young men.

Andy shares his journey to Christ, his introduction to the doctrines of grace, and the work God is doing through a Reformed church in the heart of one of the world’s most influential university cities. He also reflects on what young people are searching for today: authenticity, substance, transcendence, community, and beauty.

Grant and Andy discuss biblical masculinity, the importance of strong preaching and sound doctrine, and why discipleship requires patient, personal investment. Rather than lowering the bar to reach young men, Andy argues that the church should offer them something deeper: the truth of Scripture, the glory of Christ, meaningful Christian community, and a vision of manhood shaped by courage, humility, conviction, and sacrifice.

What does it mean to live a disciplined, productive, and faithful Christian life? In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with pastor, author, educator, and historian George Grant to discuss a lifetime of ministry, leadership, learning, and service to Christ.

George shares the story of his conversion, his introduction to the Reformed faith, and the influence of Christian leaders such as D. James Kennedy, Francis Schaeffer, J. I. Packer, James Montgomery Boice, and R. C. Sproul. He also reflects on nearly fifty years of ministry, writing more than eighty books, planting churches, building schools, mentoring young leaders, and cultivating the habits that make sustained faithfulness possible.

Together, Grant and George explore the theology of Christian productivity, the importance of beginning small, the value of careful planning, the discipline of reading and writing, and the necessity of trusting God with the results. This conversation is a powerful reminder that Christians are not responsible for accomplishing everything at once. We are simply called to do the next right thing with diligence, zeal, and faith.

What does it take to revitalize a struggling church?

In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with Jon Benzinger, pastor of Redeemer Bible Church in Gilbert, Arizona, to discuss the biblical convictions that shaped the revitalization of his church.

Jon shares how a declining and unhealthy congregation was strengthened through a renewed commitment to the Word of God, prayer, expository preaching, biblical leadership, and intentional shepherding. He also discusses the importance of training elders, caring for church members, building strong pastoral teams, and remembering that the church belongs to Christ, not to the pastor.

This is a practical and encouraging conversation about trusting God to bring health and renewal to His church through ordinary, faithful ministry.

The conversation explores:
• Church revitalization through the Word and prayer
• The pastor as an under-shepherd of Christ
• Training and investing in elders
• Why expository preaching matters
• Preaching for transformation, not merely information
• and more …

Whether you are a pastor, church leader, or simply someone who loves the local church, this conversation offers practical wisdom for pursuing faithful, biblical ministry.

In this episode of the Unashamed Truth Podcast, Grant Castleberry shares the personal story of how he became a Calvinist through studying Scripture.

Grant reflects on how the doctrines of God’s sovereignty, election, human depravity, and grace reshaped his understanding of salvation. He also explains why these truths matter for humility, worship, evangelism, and giving all glory to God.

Ultimately, this episode is not about embracing a theological label, but about submitting our understanding of salvation to the Word of God.

In this episode of The Unashamed Truth Podcast, Grant Castleberry sits down with David Schrock, pastor of preaching and theology at Occoquan Bible Church in Virginia, and co-founder of Christ Over All, for a wide-ranging conversation about the doctrines of grace and the sovereign work of God in salvation.

David explains how the Father purposes salvation, the Son accomplishes redemption, and the Holy Spirit applies the work of Christ to His people. Together, they discuss human depravity, election, regeneration, perseverance, and especially the doctrine of definite atonement, considering what Scripture means when it teaches that Christ gave His life for "His people."

This is a thoughtful and encouraging discussion about the grace of God that saves sinners, keeps them, and brings them safely to glory. You don't want to miss it!
