If the meaning is close to "permission" or "authority," we can picture the Father raising the Son, just as the Scriptures state, and the Son taking back his own life that the Father restored to him.
You make no sense attempting that explanation. In your scenario does the Son have a choice in the matter? How do you "take back" something if you're not around to take it (i.e. dead). You make absolutely no logical sense - think about it...
You're using some of your own metaphors to explain something, rather than letting the context simply explain the verse, as you earlier slated others for. The honest answer would have been to admit that there are difficulties with whichever position you take on the subject...
Being just as candid, while the NT often portrays Jesus as having a Divine stature the whole Trinity thing is only in primitive form. If you want to get a consistent view you're going to have to drop something, as the canon of 66 shows a number of conflicts.
Personally I would show a Johannine bias and agree from personal experience with the authenticity of Thomas' [late-recorded] reaction in John 20:28.
