Arcana Coelestia #15
15. Throughout heaven they do not know any other Father than the Lord, for They are one, as He Himself has said,
I am the way, the truth, and the life. Philip said, Show us the Father. Jesus said to him, Have I been with you so long, and yet you do not know Me, Philip? He who has seen Me has seen the Father. So why do you say, Show us the Father? Do you not believe that I am in the Father and the Father in Me? Believe Me that I am in the Father and the Father in Me. John 14:6, 8-11.
2 Corinthians 4:6
6
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.
