Wow, amazing first stanza. I love the contradicting images of fire and water. The continuity of this piece is nice too. Grammar wise, there are just a few errors:
1. A comma in the last stanze after human.
2. "i died but i have risen." there should be a comma after died.
3. There should be a period at the end of "i have been reborn"
I also felt this was cut short. I was expecting an epiphany and some more imagery (like in the first stanza.)

I'm guessing that the non-caps was a symbol...
It also sounds something along the lines of a story I'm writing, kinda cool really.
In the future, do you think it might be possible if I use it in my story? I'm not sure how I would... but if it comes around to that, would that be okay with you?
Granted, who knows. I may not even need a poem.
Right.
Well.

How could it be otherwise ?
When our life's been in a vice ?
For sly ways in heart device
Ways for demons to entice.

Though I'd rather white of ice
With black numbers marked in dice
Thrown twice, maybe even thrice,
To find sweet angel's disguise.
