In this episode of the Unashamed Truth Podcast, Grant Castleberry is joined by Dr. John Tweeddale, Vice President and Professor of Theology at Reformation Bible College, to explore the remarkable life and ministry of James Montgomery Boice.

Together they discuss Boice's ministry at Tenth Presbyterian Church, his influence on leaders such as R.C. Sproul, John MacArthur, John Piper, and Tim Keller, his leadership in the Chicago Statement on Biblical Inerrancy, and his role in founding the Philadelphia Conference on Reformed Theology. Along the way, they reflect on Boice's preaching, his passion for mentoring younger pastors, and why his example remains so needed for the church today.

Whether you're a pastor, ministry leader, or simply want to learn from one of the most influential yet underappreciated figures of the twentieth century, this conversation will encourage you to stand firmly on the authority of God's Word and faithfully proclaim Christ to the next generation.

What does it mean to be justified before God? Is forgiveness enough, or do believers need something more?

In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with Dr. Mike Riccardi, Professor of Theology at The Master's Seminary and a pastor at Grace Community Church, for a rich discussion on the doctrine of justification by faith alone.

Sproul and John MacArthur.

Dr. Riccardi explains the biblical foundations of imputation, the difference between Christ's active and passive obedience, and why the believer's assurance rests entirely on the finished work of Christ rather than personal performance. This conversation is both deeply theological and profoundly pastoral, offering comfort and confidence to every Christian struggling with guilt, doubt, or self-righteousness.
