god already given his glory to jesus before jesus born and god will always given glory for jesus.

Some Greeks who had come to Jerusalem for the Passover celebration and They went to Philip (who was from Bethsaida in Galilee) and told him, "Sir, we would like to see Jesus." then Philip came and told Andrew: and then Andrew and Philip told Jesus. And Jesus answered them, saying, "The hour has come for the Son of Man to be glorified. I tell you the truth, unless a kernel of wheat falls to the ground and dies, it remains only a single seed. But if it dies, it produces many seeds. Those who love their life in this world will lose it. Those who care nothing for their life in this world will keep it for eternity. If anyone serves me, he must follow me; and where I am, there will my servant be also. If anyone serves me, the Father will honor him. “Behold, now my soul is troubled, and what shall I say: My Father, deliver me from this hour? But for this I have come to this hour.” “Father, glorify your name.” And a voice was heard from Heaven: “I have glorified and I am glorifying it again.” And the crowd that was standing there heard, and they were saying, “It was thunder”, and others were saying “An Angel spoke with him.” Then Jesus told them, "The voice was for your benefit, not mine. The time for judging this world has come, when Satan, the ruler of this world, will be cast out. And When I have been lifted up from the earth, I will draw all people toward me." This he said, signifying what death he should die. then The crowd responded to him, "We have heard from the Scriptures that the Messiah will remain here forever. So how can you say, 'The Son of Man must be lifted up from the earth'? Who is this 'Son of Man'?" Jesus answered the crowd, "The light will still be with you for a little while. Walk while you have light so that darkness won't defeat you. Those who walk in the dark don't know where they're going. Put your trust in the light while you have it, so that you may become sons of light." When he had finished speaking, Jesus left and hid himself from them. source from bible, John 12:20-36
