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. Together they explore why the righteousness of Christ is essential to the gospel, how Christ's perfect obedience is credited to believers, and why this doctrine was so passionately defended by Reformers such as Martin Luther and John Calvin, as well as modern voices like R.C. 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.
