What would you say are the meanings of those lyrics ("We Take It From The Living" by Powerwolf)?

[Tammuz]

We take it from the living

We came out of storm and nightmare
Of blood and snow
Are you guided by the bible?
I want to know...

Would you die for Heavy Metal?
Then hear our call
Raise your horns for master Satan
Till the heavens fall

We take it from the living

We came out of dark and fire
From down below
All we need is merchandisers
I want to know...

Will you die for Heavy Metal?
We'd sell you all
Raise your notes for great consume
In our metal mall

We take it from the living

I really, really like this song. Fantastic vocals.

However, what would you say the meanings of the lyrics are? Do they even have a coherent meaning at all? I know that this band often sings sarcastically (as I perceive it anyways) about religion, so I would guess the Bible and Satan references aren't completely serious.
