Unashamed Truth

On this episode, Grant Castleberry sits down with worship leader, songwriter, and author Bob Kauflin for a rich conversation on worship, the affections, and the heart of Christian discipleship. Drawing from decades of ministry with Sovereign Grace Churches and Sovereign Grace Music, Bob reflects on his testimony and the development of a deeply biblical philosophy of corporate worship.
Together, Grant and Bob discuss the difference between emotional manipulation and genuine spiritual affections, the dangers of performance-driven worship culture, and why faithful worship leadership must flow out of the local church. They also explore the role of pastors in shaping congregational worship, the influence of thinkers like Jonathan Edwards and Martyn Lloyd-Jones, and how the truths of the gospel fuel lasting joy and reverence in the Christian life.
This conversation is both theological and deeply pastoral, encouraging believers to worship God in spirit and truth with hearts captivated by the glory of Christ.

In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with Matthew Bingham to explore the depth and richness of true Christian spirituality. Drawing from Bingham’s book "A Heart of Flame for God," the conversation confronts the shallowness often found in modern evangelicalism and addresses why many are tempted to look toward Roman Catholicism or Eastern Orthodoxy for greater depth.
Rather than abandoning Protestant roots, Bingham makes a compelling case for recovering the treasures of the Reformed tradition. He introduces what he calls the “Reformation Triangle”—Bible intake, meditation, and prayer—as the ordinary means by which believers grow in communion with God. Together, they discuss how these simple yet profound disciplines form a deeply biblical and historically grounded path for spiritual maturity.
