 2 Corinthians 4.6 says, "...for God, who commanded the light to shine out of darkness, hath shined in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ." And it says we're supposed to grow in that knowledge. We have the knowledge of Christ, but it doesn't stop when we come to know Him as our Savior. We're to grow in that knowledge. 2 Peter 3.18 says, "...but grow in grace in the knowledge of our Lord and Savior Jesus Christ."
