You can be physically blind but spiritually aware, and you can also have physical vision, but be spiritually blind. In the story from John 9, Jesus heals a physically blind man, but raises the ire of the religious leaders who He clearly shows to be spiritually blind! This is an amazing story, with application to us today--where are we spiritually blind even if we have our "sight", or have we not had our eyes opened to the truth for the first time?
