Some questions we ask are of others are very important, most of all to us. In this case (c. AD 30) the Pharisees, a politico-religious party, are questioning Jesus in the Jerusalem Temple. He has just told them that his father had so arranged the past 2,000 years of their national history that there were repeated promises about the Lord God above descending to bless the world.
By asking, “Where is your father?” they may have been hoping that he would say something like ‘in heaven above’ whereupon they would have arrested him for falsely claiming to be God above.
Jesus answered, “You discern neither me nor my father! If you had discerned me, you had discerned my father also.” These messages he spoke in the treasury, teaching in the temple, and no one took him, in that his hour had not yet come.
He merely pointed out that they had made it clear that they have not discerned him or the father.
So he said to them again, “I myself am going away, and you will seek me and will die in your sin. Where I myself go away you are not able to come!”
Jesus again addresses the whole Judean crowd and repeats his original message. He is going above. They will die in their sins. They are not able to go above.
