Quick answer

Idolaters do not know or understand because their eyes are shut and hearts closed. It traces idolatry to spiritual blindness and a darkened mind.

Overview

The root of idolatry is not mere ignorance but a heart and eyes that cannot perceive. Their inability to reason is itself a judgment of spiritual darkness. This blindness reveals humanity's deep need for God to open eyes, a work accomplished by the light of Christ.

Christ at the center

Isaiah sees him most clearly: the virgin's son Immanuel, the child on David's throne, the shoot from Jesse, the light to the nations, and above all the Suffering Servant pierced for our transgressions (ch. 53).

How Isaiah 44:18 points to him is part of the one story that runs through all Scripture — meet Jesus at the heart of the web, or follow a trail that traces him from Genesis to Revelation.
