What does the Bible say about having our understanding enlightened?

Ephesians 1:15-20 illustrates the notion that our understanding can only be enlightened through the divine gifts from God, specifically the spirit of wisdom and revelation. Without God's intervention, we are like the blind man who cannot see the beauty of His glory or the truth of the Gospel. This enlightenment is essential for recognizing our need for Christ, leading us to a realization of righteousness, holiness, and our own sinfulness. Understanding begins with God opening our eyes to the truth of who He is and what we need for salvation.
