What does the Bible say about spiritual light?

The concept of spiritual light in the Bible is profoundly centered on Jesus Christ. In John 12:46, Jesus declares, 'I am come a light into the world, that whosoever believeth on me should not abide in darkness.' This emphasizes that through faith in Him, believers are brought out of spiritual darkness into the light of eternal life. The light symbolizes truth and revelation, as seen throughout John's Gospel, where Jesus explains that He embodies the very essence of life and salvation, shedding light on our sinful condition and offering redemption.
