Sinners are blind to their spiritual slavery.
In this clip, Neo meets with Morpheus for the first time. Morpheus knows that Neo is looking for answers to the strange feeling he's always had that something's not quite right. Morpheus explains that the truth is around Neo at all times even though he can't see or touch it. He explains that Neo is blinded to his slavery by an unseen force. Neo can't simply be told the truth but must accept it for himself in order to believe it.
