What is Unashamed Truth really about?

In this episode, Grant Castleberry defines the heart and mission of Unashamed Truth by walking through six biblical contrasts that shape the ministry—local church over platform, depth over numbers, confessional faith over innovation, God-centered over man-centered ministry, experiential Christianity over dead orthodoxy, and gospel over Phariseeism.

This episode lays the foundation for everything Unashamed Truth stands for: biblical clarity, bold conviction, and Christ-centered discipleship.

Grant Castleberry is joined by theologian and pastor Andy Naselli for a clear, biblical conversation on the doctrine of predestination. Together they unpack what Scripture teaches about election, God’s sovereignty, human responsibility, and why this doctrine leads to deeper worship rather than fatalism.

The episode also explores how God’s sovereign grace fuels evangelism, missions, and confidence in ministry, while addressing common objections to Reformed theology. This thoughtful discussion will challenge your assumptions, strengthen your faith, and magnify the greatness of God.

What truly defines a successful church: numbers or faithfulness?

In this episode of the Unashamed Truth Podcast, Grant Castleberry challenges the modern obsession with church growth and calls believers back to biblical discipleship. Drawing from Scripture and the example of the early church, Grant argues that Jesus is far more concerned with the maturity of His people than the size of the crowd.

You’ll hear a clear critique of shallow, seeker-driven models, a warning against manufactured growth, and an introduction to the “Power Sweep” discipleship framework that prioritizes Christlike character, doctrinal depth, and spiritual formation.

If you care about healthy churches, serious discipleship, and lasting gospel fruit, this episode is for you.

In this episode of the Unashamed Truth Podcast, Grant Castleberry is joined by cultural commentator and podcast host Will Spencer for a timely and necessary conversation on the resurgence of anti-Semitism, particularly within segments of the political right.

Will shares his remarkable testimony, from growing up in a Jewish home, to years immersed in New Age spirituality, to his conversion to Christ in 2020. Drawing on history, theology, and cultural analysis, he helps define what anti-Semitism actually is, distinguishing between ethnic hatred and what he calls “worldview anti-Semitism”—the belief that Jews are uniquely responsible for the moral, cultural, and economic decay of the West.

Together, Grant and Will discuss:
• The historical roots of modern anti-Semitic conspiracy theories
• Holocaust denial and why it persists
• The influence of online subcultures and radicalized media ecosystems
• How resentment, bitterness, and scapegoating take hold among young men
• The Israel–Gaza conflict and how Christians should think biblically and soberly about Israel
• Romans 9–11, evangelism to Jewish people, and the dangers of abandoning Christian charity and truth

This episode is both a warning and a pastoral exhortation. Christians are called to reject lies, resist bitterness, love truth, and remain anchored in Scripture—especially when cultural confusion and spiritual deception are on the rise.

In this episode, Grant reflects on several key themes shaping Christian life and doctrine today. He shares about completing his PhD on Martyn Lloyd-Jones and the preacher’s lasting influence on evangelicalism. He then turns to Luke 2, unfolding the humility of Christ’s birth and the wonder of the incarnation—God’s Son entering the world in poverty and weakness for our salvation.

Grant also addresses Kirk Cameron’s recent embrace of annihilationism (conditionalism), a view that denies the reality of eternal conscious punishment. With biblical clarity, he walks through the passages that uphold eternal judgment, emphasizing the seriousness of sin, the holiness of God, and the urgent need for faithful evangelism.

If you’re seeking steady, biblical conviction in an age of confusion, this conversation will anchor your heart in truth.

In this powerful episode, Grant Castleberry sits down with Doug McCary, founder of HisLight International Ministries and host of SWAT Radio, for a candid and biblical discussion on the roles of men and women, biblical complementarianism, and the growing cultural confusion around gender and sexuality.

Doug’s story is remarkable—Marine Corps pilot, FBI agent, missionary, and evangelist. After surviving a near-fatal bird strike while flying an AV-8B Harrier, God redirected Doug’s life toward ministry, equipping him to lead men with boldness and conviction. Today, through HisLight and SWAT Radio, he challenges men to stand for truth and live as spiritual warriors for Christ.

Together, Grant and Doug talk about:

• What Scripture teaches about the roles of men and women
• The importance of male leadership in the home and church
• How Christians can hold the line on biblical truth in the face of cultural pressure
• John MacArthur’s convictions on women preaching and why they matter
• How men can lead with humility, courage, and grace in a confused world

Doug’s life and ministry are a living testimony of faith under fire—literally and spiritually. You’ll be encouraged, challenged, and equipped to live as a faithful disciple in an age of compromise.

In this episode of the Unashamed Truth Podcast, Grant Castleberry explores the opening chapters of Genesis to uncover the roots of a distinctly Christian and biblical worldview. What does it mean to be made in the image of God? Why does the doctrine of creation matter for how we view life, morality, gender, marriage, and human purpose?

Genesis is not just the beginning of the Bible—it’s the beginning of everything. In a culture that often rejects biblical authority, returning to the opening chapters of Scripture helps us recover the truth about who God is, who we are, and why it all matters.

In this episode of the Unashamed Truth Podcast, Grant Castleberry walks through what it means to have a truly Christian worldview—and why it's essential for every believer.

He reminds us that the Christian worldview brings wisdom, joy, and strength for life’s trials as we submit every thought to the authority of God’s Word.
