Jesus proved to the Jews that Abraham was not their father, and he lead them to discern the name of the actual father they were following. As he was, so they were also.
The Jews felt that Jesus had made plain the difference between him and them. They replied that they were not the children of fornication, unlike the Moabites and Ammonites who were born of incest (Genesis 19:36–38). Nor were they a mixed race like the Samaritans, since they claimed that God was their Father, relying on the passage in Exodus 4:22 and Deuteronomy 32:6 as well as Isaiah 63:16. When Jesus pointed out that God was his Father, they retorted that he was their Father also according to Scripture. This was a doctrine of their faith, for which they had struggled and suffered. But their witness was false.
Jesus demonstrated briefly that they were deceiving themselves. He said, "If God were your Father, you would have loved me, because God is love not hate. He loves His Son who proceeds from Him, and the Son carries His essence." Jesus was not independent of the Father even for a moment, but obeyed Him as an obedient apostle.
Then Jesus asked the multitude, "Why do you fail to understand my language? I do not speak in alien tongues, but I offered my Spirit in simple words, that even the little ones would grasp." Jesus answered his own question, saying to his enemies, "You cannot listen; you are not free but slaves; your spiritual lives are lost. You resemble the deaf who do not hear the call."
Dear brother, how is your hearing spiritually, do you hear God’s word in your heart? Do you hear His voice eager to cleanse and order your inner being? Or are you proud and deaf, because a strange spirit has taken hold of you? Do you work for God in the power of the Gospel, or does an evil spirit indwell you, and you follow its directions?
