From the Bible:
Chapter 1 of the Gospel of St. John states:
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name.
From the Bhagavad Gita, tenth Chapter:
To those who are ever attached to Me, and who worship Me with love, I impart discernment, by means of which they attain Me.
Out of my love for them, I, the Divine within them, set alight in them the radiant lamp of wisdom, thereby dispelling the darkness of their ignorance.
