At Christmas, Christians often quote Isaiah 7:14—“the virgin will conceive and give birth to a son”—but few pause to ask what that verse meant for King Ahaz before it pointed to Christ. In this episode of Thinking Christian, Dr. James Spencer walks through the political and spiritual crisis facing Judah, the rising Assyrian threat, and Ahaz’s refusal to ask God for a sign.

James unpacks why God answered with something that seemed wildly inadequate in the face of war: a child. He explores how this sign functioned as both judgment and hope, how the language of “young woman” and “virgin” works in Hebrew and Greek, and why Matthew is not ripping Isaiah 7:14 out of context when he applies it to Jesus.

Along the way, you’ll see how prophetic patterns ripple across Scripture, how our expectations of power clash with God’s humble ways, and how the virgin birth reveals a Savior who comes not with military might, but with a presence that judges and delivers. Perfect for thoughtful Christians wanting to go deeper this Christmas.
