John 8: 12 - 20 To Know The Father, You Must Know The Son

Then Jesus again spoke to them, saying, “I am the Light of the world; he who follows Me will not walk in the darkness, but will have the Light of life.”  So the Pharisees said to Him, “You are testifying about Yourself; Your testimony is not true.”  Jesus answered and said to them, “Even if I testify about Myself, My testimony is true, for I know where I came from and where I am going; but you do not know where I come from or where I am going. You judge according to the flesh; I am not judging anyone.  But even if I do judge, My judgment is true; for I am not alone in it, but I and the Father who sent Me.  Even in your law it has been written that the testimony of two men is true.  I am He who testifies about Myself, and the Father who sent Me testifies about Me.”  So they were saying 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.”  These words He spoke in the treasury, as He taught in the temple; and no one seized Him, because His hour had not yet come.
The central difference in this conversation is that the Pharisees are trying to judge Jesus in the flesh, by their own experience, but apart from the Law of the Covenant.  As Jesus said, where ever two testify about something it is true and Jesus testifies about His identity and so does the Father.  Jesus has done nothing to disqualify Himself as the Promised Messiah and even when judged by Rome, Pontious Pilate said he found no guilt in Him. Yet the people's heart was hardened and they sought to do their part in prophecy and slay the Lamb of God who came to take away the sins of the world.
Daily Prayer:  Lord Jesus, it is easier to understand in hindsight because You were indeed slain, but in a human and divine manner raised Yourself from the dead assuring victory over death and its consequence of sin to all those who received You for who You are which is the Son of Man and the Son of God.  In Your holy name I pray Amen.
