2 Corinthians 4:6
For it is the God who commanded light to shine out of darkness, who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.

2 Corinthians 8:7
But as you abound in everything—in faith, in speech, in knowledge, in all diligence, and in your love for us--see that you abound in this grace also.
