I think you've said something very profound here in such a beautiful and creative way. The summary line,

"Belief transfers Life through, beyond, in spite of, overthrowing Death's power in our physical"

is eloquent of the power of belief. The whole poem rings to me of "Lord, I believe. Help thou my unbelief." It hits me powerfully soft, like a strong wave in the surf, the savor of salt left in my mouth.
