Jesus gave them this answer:

1.(In Action : You have all authority but still you respect the instructions given:)

“Very truly I tell you, the Son can do nothing by himself.

2. (Approved actions with reference:)

He can do only what he sees his Father doing, because whatever the Father does the Son also does. 

3. (Advantages for special reasons, Benefits and Perks:)

For the Father loves the Son and shows him all he does. Yes, and he will show him even greater works than these, so that you will be amazed. 

4. (Jesus Judge the unrighteous:)

Moreover, the Father judges no one, but has entrusted all judgment to the Son.

And he has given him authority to judge because he is the Son of Man.

5. (Right judgement/ Way to be righteous:)

By myself I can do nothing; I judge only as I hear, and my judgment is just, for I seek not to please myself but him who sent me.

John 5:6‭, ‬18‭-‬20‭, ‬22‭, ‬26‭-‬27‭, ‬30.
