Unforgiving Debtor

Here I am, with bleeding fingers and shaking hands.
I prayed to God, for both our sakes, that I'd never see you again, but here I am.
Here I am.
There you are, standing as tall as your guard.
I prayed to God, for my own sake, that you'd never be too far, but there you are.
There you are.
So here I am, in debt to none,
and all I have is what I've done.
You are all that I am not,
cause You forgave and I forgot.
So bind my hands and have me leave;
I'll pay You back with gnashing teeth
and broken apologies.
I'm sorry.
