John 12:36-40

Twentieth_Century(i) 36 While you still have the Light, believe in the Light, that you may be 'Sons of Light.'" After he had said this, Jesus went away, and hid himself from them. 37 But, though Jesus had given so many signs of his mission before their eyes, they still did not believe in him, 38 In fulfillment of the words of the Prophet Isaiah, where he says--'Lord, who has believed our teaching? And to whom has the might of the Lord been revealed?' 39 The reason why they were unable to believe is given by Isaiah elsewhere, in these words-- 40 'He has blinded their eyes, and blunted their mind, so that they should not see with their eyes, and perceive with their mind, and turn--And I should heal them.'
