Author Don Schwager, Servants of the Word - John 8:12-20 - Again Jesus spoke to them, saying, "I am the light of the world; he who follows me will not walk in darkness, but will have the light of life." The Pharisees then said to him, "You are bearing witness to yourself; your testimony is not true." Jesus answered, "Even if I do bear witness to myself, my testimony is true, for I know where I have come and where I am going, but you do not know where I come or where I am going.
