​¹²Again Jesus spoke to them, saying, "I am the light of the world. Whoever follows me will never walk in darkness but will have the light of life." ¹³Then the Pharisees said to him, "You are testifying on your own behalf; your testimony is not valid." ¹⁴Jesus answered, "Even if I testify on my own behalf, my testimony is valid because I know where I have come from and where I am going, but you do not know where I come from or where I am going. ¹⁵You judge by human standards I judge no one. ¹⁶Yet even if I do judge, my judgment is valid; for it is not I alone who judge, but I and the Father who sent me. ¹⁷In your law it is written that the testimony of two witnesses is valid. ¹⁸I testify on my own behalf, and the Father who sent me testifies on my behalf." ¹⁹Then they said to him, "Where is your Father?" Jesus answered, "You know neither me nor my Father. If you knew me, you would know my Father also."
