Jesus has just healed the paralysed man at Bethesda and the Jewish leadership has attempted to rebuke him for doing so on the Sabbath. The Jewish perception of what could be done on the Sabbath was a poor interpretation, although a valid one as those who taught it did have the legal right to “bind and loose” the rules. Their interpretation comes from God’s order of things during the seven days of creation. On the seventh day God rested. Therefore all must rest on the Sabbath, this does not contradict helping ones neighbour or curing the sick. God obviously doesn’t take Saturdays off in an absolute sense because people still die and are born on the Sabbath, that means giving life on the Sabbath which would include curing the sick, feeding the poor and taking care of the needy does not break any laws at all.
17 But Jesus answered them, “My Father is working still, and I am working.”
18 This was why the Jews sought all the more to kill him, because he not only broke the sabbath but also called God his Father, making himself equal with God.
Even though it is the Sabbath, God the Father is obviously still working. Things still exist, people still die and are born. Jesus uses simple language to explain this by referring to it as if its normal work, something people should be able to comprehend. Jesus explains that the reason why he is giving life on the Sabbath (healing the paralysed man) is because his Father in heaven does the same. He as the son always does can only do what his father does. It’s a simple formula but its depths has entire books written on the subject. For the Second Temple Jews hearing this, it is very grating, to us who have been formed by trinitarian thinking we just say “oh yeah, that makes sense” but to them this is extremely painful to deal with, in fact it just makes them more angry at Jesus. By using this father/son language Jesus is of course making himself the same kind as the Father in heaven (God). This would make him God as well or otherwise another god. All very difficult for a first century Jew to understand with his own power and he’s saying this all the while he is “breaking” the rules of the Sabbath, at least to their understanding.
19 Jesus said to them, “Truly, truly, I say to you, the Son can do nothing of his own accord, but only what he sees the Father doing; for whatever he does, that the Son does likewise.
Jesus begins with his Aramaic preface “Amen Amen” sometimes translated as “Truly, truly”. He does this whenever he is about to say something extremely important. He is about to explain, as much as you in human words, the mystery of the relationship between the father and son. The Son (Jesus) can do nothing by himself but only what he sees his father do. Like a biological father/son relationship except we know in the non-divine relationship such a mechanism is not absolute.
A son can literally do things by his own accord and can fail in imitating his father, but as Jesus does elsewhere, he uses language we can comprehend to explain what we cannot. We can have faith, live by these words, and it not be a lie because it isn’t one, there is simply no way this side of Heaven for us to comprehend these mysteries except through the model given to us by Jesus. This is what we call “divine condescension”.
In short. Jesus gives life on the Sabbath because his Father does.
20 For the Father loves the Son, and shows him all that he himself is doing; and greater works than these will he show him, that you may marvel.
21 For as the Father raises the dead and gives them life, so also the Son gives life to whom he will.
Why does the Son imitate the Father perfectly? Because the Father loves the Son perfect, and shows him all that he himself does. The Son has seen things more marvellous than the miracles the people on earth have witnessed. The Son, again, gives life to whom he will because the Father can raise the dead and give life. His ability is from his partaking of the trinity.
22 The Father judges no one, but has given all judgment to the Son,
23 that all may honor the Son, even as they honor the Father. He who does not honor the Son does not honor the Father who sent him.
All judgement has been given to the Son. This was prophesied by Daniel, the Son of Man who would receive of dominion and power from the Ancient of Days. Jesus is the Son of Man, the Father in heaven is the Ancient of Days. Judgement ultimately rests in the hands of a king, an office given to the Son by the Father. Because a son is a perfect representative of the Father, anyone who dishonours the son is by extension dishonouring the father.
24 Truly, truly, I say to you, he who hears my word and believes him who sent me, has eternal life; he does not come into judgment, but has passed from death to life.
25 “Truly, truly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God, and those who hear will live.
Two more “amen amen” statements. Whoever hears and by extension comprehends what Jesus is saying has eternal life. If you hear and understand you will do what is required. It’s not like you can just intellectually assent, Jesus says on far too many other occasions that it doesn’t work that way. So these statements can’t be taken out of that foundational context. Those that understand and therefore do what is required do not come into judgement, that is negative judgement and will pass from death to life.
The dead will hear Jesus’ voice and live. It’s hard to tell whether Jesus is speaking about those in the old covenant who do not have eternal life yet or if he is speaking of those who are literally dead who will receive life in the resurrection, later verses may indicate the latter.
26 For as the Father has life in himself, so he has granted the Son also to have life in himself,
27 and has given him authority to execute judgment, because he is the Son of man.
All the lifegiving power that Jesus has comes from God the Father because it is from “in himself”. It has been granted to Jesus so may also have the same life in himself. His power is not independent but relational.
28 Do not marvel at this; for the hour is coming when all who are in the tombs will hear his voice
29 and come forth, those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of judgment.
They should not marvel at this “ability” for lack of a better word, because it is something they will all share if they reach the beatific vision, heaven. The dead will see God face to face, as he truly is. Something currently reserved for Jesus the son.
Jesus explicitly says “those who have done good” so again, that statement previously that people misinterpret really shouldn’t be unless they’re purposefully ignoring what comes straight afterward. Those who do good go to the resurrection of life, that is eternal life and those who have done evil go to judgement, specifically damnation.
30 “I can do nothing on my own authority; as I hear, I judge; and my judgment is just, because I seek not my own will but the will of him who sent me.
Jesus’ position and power is entirely dependant on his relation to the father. This is a mystery of the trinity. His judgement cannot be mistaken as its finalities are in line with the will of God the Father. Perfect son, perfect obedience to the Perfect Father with Perfect power.
