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.

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.
