I am no slave

I am not your servant.
I am a child of the Most High;
Praying for you day and night.

I am no prisoner.
Nor am I your slave;
What keeps me from being free?

You keep track of my flaws.
Then you betray my trust;
Have you lost your soul?

You complain about my presence.
Yet, you worry about my plans;
Refer to your own venomous tongue.
