Context
34 The multitude answered him, “We have heard out of the law that the Christ remains forever. How do you say, ‘The Son of Man must be lifted up’? Who is this Son of Man?”
35 Jesus therefore said to them, “Yet a little while the light is with you. Walk while you have the light, that darkness doesn’t overtake you. He who walks in the darkness doesn’t know where he is going.
36 While you have the light, believe in the light, that you may become children of light.” Jesus said these things, and he departed and hid himself from them.
