Used repeatedly to argue that Jesus claims divine prerogatives: he does whatever the Father does, gives life, judges all, and must be honored in the same way as the Father.
bible
19 Jesus therefore answered them, "Most assuredly, I tell you, the Son can do nothing of himself, but what he sees the Father doing. For whatever things he does, these the Son also does likewise. 20 For the Father has affection for the Son, and shows him all things that he himself does. He will show him greater works than these, that you may marvel. 21 For as the Father raises the dead and gives them life, even so the Son also gives life to whom he desires. 22 For the Father judges no one, but he has given all judgment to the Son, 23 that all may honor the Son, even as they honor the Father. He who doesn't honor the Son doesn't honor the Father who sent him.
