Where do the unborn go?

Where do the unborn go?
What happens to their souls?
Do they even exist; in limbo?
Lord I know you know everything
I am such a simple heart
I don't know a lot; but this I do know! 
Oh dearest Lord you are everything
You know everything!
You made everything!
How can we poor little humans ever 
Think to understand your ways
The Bible says " We do not think as God thinks"
So true! We could never understand 
Even the tiniest part of this magnificent universe
We are puny and useless in your eyes
So then Lord; why would you even want 
To think of us; let alone love us
Poor sinners that we are
We are all that is low and simple
We are all that is sinful
And yet Lord; you love us
You are truly the most wonderful of all!
