'Enlightenment' in the Bible

For through your knowledge (spiritual maturity) this weak man is ruined [that is, he suffers in his spiritual life], the brother for whom Christ died.

For God who said, "Light will shine out of darkness," [is the one] who has shined in our hearts for the enlightenment of the knowledge of the glory of God in the face of Christ.

The purpose of this enlightenment is that through the church the multifaceted wisdom of God should now be disclosed to the rulers and the authorities in the heavenly realms.

in whom are hidden all the treasures of wisdom and knowledge [regarding the word and purposes of God].
