John 12:35; John 12:36

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." When Jesus had said these things, he departed and hid himself from them.
