That Bit of Filth

That bit of filth
Is like dirt
It builds and films
Where you're hurt

In a rut
It gets in
There's no but-
Disease begins

In a crack
It does grove
To attack
On the move

In a sore
It does play
To infect and gore
Hardening away

For inside us
It's a germ
There to pus
Boil and squirm

So just like soap
Makes us clean
The Lord's our hope
On whom we lean

He protects us well
And bears the dirt
That sins don't dwell
Nor divert

That bit of dirt
Cannot hurt
I say at first
Till... the tears burst
