Jesus makes his tremendous claim

^19-29 Jesus said to them, “I assure you that the Son can do nothing of his own accord, but only what he sees the Father doing. What the Son does is always modelled on what the Father does, for the Father loves the Son and shows him everything that he does himself, Yes, and he will show him even greater things than these to fill you with wonder. For just as the Father raises the dead and makes them live, so does the Son give life to any man he chooses. The Father is no man’s judge: he has put judgment entirely into the Son’s hands, so that all men may honour the Son equally with the Father. The man who does not honour the Son does not honour the Father who sent him. I solemnly assure you that the man who hears what I have to say and believes in the one who has sent me has eternal life. He does not have to face judgment; he has already passed from death into life. Yes, I assure you that a time is coming, in fact has already come, when the dead will hear the voice of the Son of God and when they have heard it they will live! For just as the Father has life in himself, so by the Father’s gift, the Son also has life in himself. And he has given him authority to judge because he is Son of Man. No, do not be surprised—the time is coming when all those who are dead and buried will hear his voice and out they will come—those who have done right will rise again to life, but those who have done wrong will rise to face judgment!

^27-30 They did not realise that he was talking to them about the Father. So Jesus resumed, “When you have lifted up the Son of Man, then you will realise that I am who I say I am, and that I do nothing on my own authority but speak simply as my Father has taught me. The one who sent me is with me now: the Father has never left me alone for I always do what pleases him.” And even while he said these words, many people believed in him.
