John 12:40-41 & Isaiah 6
John 12:40 (NIV) "He has blinded their eyes and deadened their hearts, so they can neither see with their eyes, nor understand with their hearts, nor turn--and I would heal them." {[40] Isaiah 6:10} 41 Isaiah said this because he saw Jesus' glory and spoke about him.
Isa 6:5 (NIV) "Woe to me!" I cried. "I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty" É10 Make the heart of this people calloused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.
