Must be

Must Be That the World's Gone Blind.
Must Be That the World's Gone Blind.
I Can't Believe That We Could See Some Things
And Just Go On With Our Lives.
Well, It Must Be That the World Is Blind

Must Be That the World's Gone Dumb.
Must Be That the World's Gone Dumb.
I Can't Believe That We Could Be So Silent
When We See What We Might Become.
Well, It Must Be That the World Is Dumb.

Must Be That the World's Gone Lame.
Must Be That the World's Gone Lame.
I Can't Believe That We Could Sit So Still
While the Furious Fan the Flame.
Well, It Must Be That the World Is Lame.

Must Be That the World's Been Saved.
Must Be That the World's Been Saved.
The Blind Will See, and the Dumb Will Talk,
The Chains Will Fall, and the Lame Will Walk,
And the Dead Will Rise From the Grave.
Well, It Must Be That the World's Been Saved,
Must Be That the World's Been Saved.
