It is often said that the body, often the "physical" body, is finite and limited; and to the untrained observer this is "true".
The body can be cut and mangled to pieces, it ages and has an ultimate end called death.
Well...sure, I mean..."yes"...
What's your point?
Usually a reference to finite being is in response to a question on the infinite.
If a particularly precocious child, who is beginning to see beyond their particular religious upbringing, asks about these issues of "limitations" the adult will certainly convey to the child in a particular Occam's Razor way and cut straight to the heart of the matter and on top of that, will give them a kid friendly, easily digestible, practical scenario:
"In our spiritual bodies, there will be 'no limits'; you can do anything you want."
"You know how you can't walk through walls now? You will certainly be able to."
Iconoclasts and heretics have been derided throughout history for obvious reasons since they disrupt the natural order of things, or perhaps more directly, the "control" was disrupted.
Heretics not only think differently themselves, but they seem to get an exponentially growing following. A heretic that has no following is a mad man who is no more a threat to anyone else but himself. This was the precarious position that Jesus occupied in 1st century Jerusalem. It obviously wasn't problematic for Jesus since he was perfectly happy with what he was doing, it was just that the leaders weren't fond of the following; stopping a following is like stopping a train, it takes a little straining.
So what ended up occuring is that Jesus was safely put in his place and was fully given all that he claimed, the only condition is that the followers wouldn't be given the same.
The Gospel, or the "Good News" was that the Kingdom of God is within. There is no searching or desiring, or need for faith.
You are the divinity.
The "condition" however shifted the divinity from "yourself" to that of the Creator (along with Jesus himself, and the ecstasy [holy spirit]).
Now that we can see this, we can obviously break it down as the situation necessitates. That is the iconoclasm.
Nothing is sacred.
...so about the "walking through walls" thing...
Why would anyone want to do that, physical or otherwise?
Are you seriously demoting the gravitas and grandiloquence of the eternal Spirit and its omniscient knowledge on the condition of being able to walk through plaster and timber framing?
That is tantamount to using the Keck Telescope at Mauna Kea Observatories to find the keys you locked in your car.
I mean...yes; while it technically is possible, why don't you use the fantastic instrument for fantastic things?
There are no problems for the spirit.
No conditions to put on it.
Nothing to be concerned with.
