John 12:31-37

Now judgment is upon this world; now the ruler of this world will be cast out. And I, if I am lifted up from the earth, will draw all men to Myself.” But He was saying this to indicate the kind of death by which He was to die. The crowd then answered Him, “We have heard out of the Law that the Christ is to remain forever; and how can You say, ‘The Son of Man must be lifted up’? Who is this Son of Man?” So Jesus said to them, “For a little while longer the Light is among you. Walk while you have the Light, so that darkness will not overtake you; he who walks in the darkness does not know where he goes. While you have the Light, believe in the Light, so that you may become sons of Light.” T hese things Jesus spoke, and He went away and hid Himself from them. But though He had performed so many signs before them, yet they were not believing in Him.
