When someone comes to faith, what’s really happening beneath the surface? Is belief simply a human choice, or the result of God’s sovereign work in the heart? In this episode of MARSCAST, Dr. J. Mark Beach joins Jared Luttjeboer once again to explore the doctrine of irresistible grace, or effectual calling: the Spirit’s life-giving summons that makes faith possible. Together, they unpack how God’s call differs from a mere invitation, how regeneration relates to faith, and how this truth brings hope for struggling believers, wandering children, and weary parents. A conversation that is both deeply theological and pastoral, this episode invites you to rest in the God who calls and overwhelms our resistance with grace.
