Based on Matthew 15:14, 1 Corinthians 4:3-6, Ephesians 4:18

Don't know where you're going but you think you know the way
20-20 vision but you can't see the light of day
Road is wide or narrow but you can't tell which is which
Blind will follow blind and you'll both end up in the ditch
Can't you see you can't see? Don't you know - you don't know?

(Chorus)

Blinded eyes can't see the light
When it's glowing in the night right in front of you
Blinded eyes can't see the truth
When it's written on the wall in plain view
Blinded eyes can't see the Son
Or the work that He has done out of love for you
Blinded eyes

Groping in the darkness searching for the missing switch
Come up empty-handed try to scratch the endless itch
There is only one light that can penetrate your mind
Just one look at Jesus could leave their scales behind
Can't you see - you could see? Don't you know - you could know?
