I LOVE THIS SONG!

To me, this song is about someone hiding from the world (obviously expressed when she says "I hide myself (in the dark)")
but it extends further than that, she is hiding from the truth and imperfections. In the silence, it is said, that the truth speaks loudest, hence she is afraid of silence, and tries to "fill this space" with "idle words", the noise hides fear.

"Now I'm mute, despite myself
All of them are gone
The silence overtakes me
The idle words forsake me and I am left to face me"

This stanza suggests that the idle words were her way of hiding, running, and ultimately avoiding her truth, and so when she is mute, everything comes rushing in, like opening the flood gates, and she is "held accountable for every idle word"

"Glory shows up, exposes us
I'm naked here, forsaken here
By the dark, by the dark"

This stanza shows that she cannot truly hide, not even in the dark, at which point she begs Jesus to kill her, and grant her redemption in the form of resurrection (so she may walk the Earth again free from sin and guilt)

TL:DR;
This song is about hiding from yourself, and ultimately finding that you can't really hide at all, that no matter what, everything will catch up to you.

I love it.
