How can an infant—devoid of cognitive reasoning, language, or the ability to process the preached Gospel—be born again? Across centuries of church history, Puritans, Particular Baptists, and Reformed giants like Charles Spurgeon, John Gill, Charles Hodge, and B.B. Warfield wrestled with this profound theological enigma. Rejecting both the error of baptismal regeneration by infant baptism, and the myth of natural innocence, these theologians pointed to something far more awe-inspiring: a sovereign, unmediated work of the Holy Spirit who transforms the soul beyond the reach of human intellect. Join us in this episode as we journey through the 1689 London Baptist Confession, historical debates, and the mechanics of divine grace to discover how God secretly regenerates the most vulnerable among us, proving that salvation is, from first to last, entirely of the Lord.
