John 12:37-41 Part 2 of 2

Even after Jesus had performed so many signs in their presence, they still would not believe in him. This was to fulfill the word of Isaiah the prophet: "Lord, who has believed our message and to whom has the arm of the Lord been revealed?" For this reason they could not believe, because, as Isaiah says elsewhere: "He has blinded their eyes and hardened their hearts, so they can neither see with their eyes, nor understand with their hearts, nor turn--and I would heal them." Isaiah said this because he saw Jesus' glory and spoke about him. 

Isaiah said this because he saw Jesus' glory 
Isaiah 6:1-4  In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple. Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. And they were calling to one another: "Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory." At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke. 
Psalm 72:19  Praise be to his glorious name forever; may the whole earth be filled with his glory. Amen and amen.
Revelation 4:8  Each of the four living creatures had six wings and was covered with eyes all around, even under its wings. Day and night they never stop saying: " 'Holy, holy, holy is the Lord God Almighty,' (Isaiah 6:3) who was and is and is to come."

and spoke about him 
Luke 24:27  And beginning with Moses and the Prophets, he explained to them what was said in all the Scriptures concerning himself.
John 1:45  Philip found Nathanael and told him, "We have found the one Moses wrote about in the Law, and about whom the prophets also wrote--Jesus of Nazareth, the son of Joseph."
