Filthy lyrics

Filthy, dirty, something that I can't explain
I'm so unworthy, this gift You give me every day
And sometimes I just can't buy
The reason why You die
Everyday to cleanse the dirt of me
And I try to get by without Your blood that covers me
And I sigh as I die with each breath eventually
And leaving no excape, I fall into Your waves
And drink the love that washes over me
How deep the flood, that washes me away
How pure the blood, I'm not filthy anymore.
And I cry oh my God what have I done
I have nailed all these nails into Your only son
And still You call me a precious lamb, a chosen one
I'm filthy and You make me clean
