Isaiah 7:10–14 speaks into a moment of fear and political crisis, where King Ahaz refuses God’s offer of a miraculous sign and chooses human alliances over faith. In response, God Himself gives a deeper promise: a child called Immanuel—“God with us”—a sign that He will remain faithful to the house of David despite the king’s unbelief. Matthew reveals the fullness of this promise in the virgin birth of Jesus Christ, the true Immanuel who embodies God’s presence with His people and brings salvation to the world.
