Quick answer

Unbelievers' minds are darkened and cut off from God's life because of ignorance and hardened hearts. Sin is rooted in a moral, not merely intellectual, blindness.

Overview

Paul diagnoses the condition of life apart from Christ: a darkened understanding, alienation from God, and hearts hardened against him. This ignorance is culpable, springing from willful resistance rather than mere lack of information. Such a portrait of human lostness magnifies the grace that brings light and life in Christ.
