Check out this commercial that BMW did using an experimental technique. They are harnessing some of the lesser known powers of light.
This gets me thinking about how often the Bible refers to God as light. 2 Corinthians 4:4-6 speaks into this idea.
“The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God. For what we preach is not ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesusâ€™ sake. For God, who said, ‘Let light shine out of darkness,’ made his light shine in our hearts to give us the light of the knowledge of Godâ€™s glory displayed in the face of Christ.”
As believers, we should be able to close our eyes and see Christ. His light should be so imprinted into our minds that we see Him whether we are looking or not.
