John 12:35-36 NIV
Then Jesus told them, “You are going to have the light just a little while longer. Walk while you have the light, before darkness overtakes you. Whoever walks in the dark does not know where they are going. Believe in the light while you have the light, so that you may become children of light.” When he had finished speaking, Jesus left and hid himself from them.
