Our understanding, which is enlightened by the Spirit of truth, should receive with purity and freedom of heart the glory of the cross as it shines in heaven and on earth. It should see with inner vision the meaning of the Lord’s words when he spoke of the imminence of his passion: The hour has come for the Son of Man to be glorified. Afterward he said: Now my soul is troubled, and what am I to say? Father, save me from this hour. But it was for this that I came to this hour. Father, glorify your Son. When the voice of the Father came from heaven, saying, I have glorified him, and will glorify him again, Jesus said in reply to those around him: It was not for me that this voice spoke, but for you. Now is the judgment of the world, now will the prince of this world be cast out. And I, if I am lifted up from the earth, will draw all things to myself.
