John 8:12-19

When Jesus spoke again to the people, he said, “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”
The Pharisees challenged him, “Here you are, appearing as your own witness; your testimony is not valid.”
Jesus answered, “Even if I testify on my own behalf, my testimony is valid, for I know where I came from and where I am going. But you have no idea where I come from or where I am going. You judge by human standards; I pass judgment on no one. But if I do judge, my decisions are true, because I am not alone. I stand with the Father, who sent me. In your own Law it is written that the testimony of two witnesses is true. I am one who testifies for myself; my other witness is the Father, who sent me.”
Then they asked him, “Where is your father?”
“You do not know me or my Father,” Jesus replied. “If you knew me, you would know my Father also.”
