With your line of thinking, you would be ADDING a lot that is not there, something I'm not prepared to do, but if that's what you chose, then so be it.

Then you go on to do just that in the next two paragraphs of this post.

Don't loose sight of the fact as well, it was the man Jesus speaking of himself, in the here and now of the times.
Not to mention, a man caused the problem, that would suggest that God would use a man to correct it, to show and nail the opposition, that one lower than him, can do what he failed to do = case closed Satan, your fair trial is over , no appeal. lol.

The verse following 3:13 and considering the one before it, that they wouldn't believe a heavenly thing, if he told them (which he does), imo shows that Jesus is in effect, giving a prophesy of what was going to happen (3:14 demands this thought), regarding him and him finishing up in heaven at the RHS of God as the scriptures tell us.

Yes. In your opinion (imo) is not adding your opinion. Really?
