5:19 Then answered Jesus and said unto them, Verily, verily, I say unto you, The Son can do nothing {d} of himself, but what he {e} seeth the Father do: for what things soever he doeth, these also doeth the Son {f} likewise.
(d) Not only without his Father's authority, but also without his mighty working and power.
(e) This must be understood of the person of Christ, which consists of two natures, and not simply of his Godhead: so then he says that his Father moves and governs him in all things, but yet nonetheless, when he says he works with his Father, he confirms his Godhead.
(f) In like sort, jointly and together. Not because the Father does some things, and then the Son works after him and does the same, but because the might and power of the Father and the Son work equally and jointly together.
5:19-21 Then answered Jesus. To their charge of blasphemy. He shows that there is the closest co-operation between the Father and Son. What the Father does the Son will do, even to the extent of giving life to the dead.
5:19 The Son can do nothing of himself - This is not his imperfection, but his glory, resulting from his eternal, intimate, indissoluble unity with the Father. Hence it is absolutely impossible, that the Son should judge, will, testify, or teach any thing without the Father, John 5:30, and c; John 6:38; John 7:16; or that he should be known or believed on, separately from the Father. And he here defends his doing good every day, without intermission, by the example of his Father, from which he cannot depart: these doth the Son likewise - All these, and only these; seeing he and the Father are one.
5:17-23 The Divine power of the miracle proved Jesus to be the Son of God, and he declared that he worked with, and like unto his Father, as he saw good. These ancient enemies of Christ understood him, and became more violent, charging him not only with sabbath-breaking, but blasphemy, in calling God his own Father, and making himself equal with God. But all things now, and at the final judgment, are committed to the Son, purposely that all men might honour the Son, as they honour the Father; and every one who does not thus honour the Son, whatever he may think or pretend, does not honour the Father who sent him.
