John 12:35-36

35So Jesus said to them, “The Light is among you [only] a little while longer. Walk while you have the Light [keep on living by it], so that darkness will not overtake you. He who walks in the darkness does not know where he is going [he is drifting aimlessly].

36While you have the Light, believe and trust in the Light [have faith in it, hold on to it, rely on it], so that you may become sons of Light [being filled with Light as followers of God].” Jesus said these things, and then He left and hid Himself from them.
