27 “Now is my soul troubled. And what shall I say? ‘Father, save me from this hour’? But for this purpose I have come to this hour. 28 Father, glorify your name.” Then a voice came from heaven: “I have glorified it, and I will glorify it again.” 29 The crowd that stood there and heard it said that it had thundered. Others said, “An angel has spoken to him.” 30 Jesus answered, “This voice has come for your sake, not mine. 31 Now is the judgment of this world; now will the ruler of this world be cast out. 32 And I, when I am lifted up from the earth, will draw all people to myself.” 33 He said this to show by what kind of death he was going to die. 34 So the crowd answered him, “We have heard from the Law that the Christ remains forever. How can you say that the Son of Man must be lifted up? Who is this Son of Man?” 35 So Jesus said to them, “The light is among you for a little while longer. Walk while you have the light, lest darkness overtake you. The one who walks in the darkness does not know where he is going. 36 While you have the light, believe in the light, that you may become sons of light.” (John 12:27-36)
Father glorify your name. This whole passage is about Christ’s crucifixion through which the Father will be glorified. The Father is glorfied there because it is through the cross that his creation is redeemed and finally restored. It was for this purpose Jesus came he says. The people understand what he is talking about and they think his death will be the end of his kingdom, perhaps before it is even begun. How can you be lifted up if the Christ’s kingdom will last forever? Jesus doesn’t argue or dispute. He offers his gospel and lets it stand. There is light now, walk now. Darkness will overtake you otherwise. The light is here now, now is your opportunity to believe. If you believe you becomes sons of light even as he is light of light and very God of Very God. But if you do not believe, and reject than the gospel does not stay forever, darkness will overtake you and you will no longer be able to believe. But now that light goes to the cross to glorify his Father.
