<p>12:35 <i>Jesus replied to them: Yet a little while is the light among you. Walk while you have the light, so that darkness does not overtake you. He that walks in the darkness does not know where he goes- </i>He had earlier spoken of Himself as the light of the world, meaning a torch lifted up, just as the snake was lifted up on a standard pole. And He had spoken this in evident anticipation of the manner of His death. Yet He speaks as if He was in His life the light of the world, by which men must walk; the prologue introduces this theme. His life exhibited the spirit of His final death. And this is the light, lifted up, by which we must live. There can be no sense of direction to life unless it is guided by the principles of the cross- we will know not whither we go. For those whose lives seems a long tunnel, through reason of their jobs or family burdens, let His cross enlighten our darkness. The light of His example was literally only to be with them a few more days before He would die. The darkness which could overtake them was that of Judaism, according to the prologue; and John's letters define that darkness as hating our brother. For those Jews to not accept the Lord as their Messiah and to crucify Him, and then persecute His followers, is all not living in love towards our brother. This is to live in darkness.</p>
