Ignorance is rooted in hardness, not the other way around. Therefore we are not excused. The problem with our ignorance of God’s beauty is not innocent unawareness, but culpable hardness. Our hardness is our deadness, and our deadness makes us unable to submit to the command, Love the Lord with all your heart.
