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.

In this episode, Grant Castleberry turns to a question many Christians have wrestled with at some point. How should a believer think about alcohol?

With careful attention to Scripture and years of pastoral experience, Grant walks through what the Bible actually says. He shows that alcohol is presented as a gift from God, yet also carries serious warnings when it is misused. The issue is not simply drinking, but the loss of self-control that leads to drunkenness and its consequences.

This conversation moves through several key themes.

• What Scripture teaches about enjoying God’s gifts.

• The real dangers and damage caused by alcohol abuse.

• The call for believers to live sober-minded and disciplined lives.

• The importance of loving others well by considering the weaker brother.

• And the role of wisdom, especially for those in leadership.

This is a thoughtful and honest episode that brings biblical clarity to a complicated issue.
