John 12:35-36

35Jesus answered, ‘The light will be with you for only a short time longer. So continue to walk while you still have the light. Do that, so that the dark will not come over you. Anyone who walks in the dark does not know where they are going.

36While you still have the light with you, believe in that light. So then you will become children of light.’ When Jesus had said this, he went away. He hid himself from them.
