Analysis of Why am I mightily used by God

Here is the question
Why am I mightily used by God?
From what I know God ain't blind or deaf
Then here is my question
Father have you not heard about my sin or seen them or you just choose to overlook and bless me and use me any way?
Lord have you considered my background or perhaps my past?
Lord I'm available for the new revelation
One thing I learned about you is that you never run out of favor
You there when I don't see you
You there when I don't feel you
It humbles my heart to be known by you not to mention to be used.

Here is the question again
Why am I mightily used by God?
You bless me and use me in strange places
You always put me in the right places at the right time
I enter in the room full of sick people but before I leave everyone is cured
I'm an encourager even when myself needs encouragement
I'm not taking any glory or credit but it belongs to you
I can not thank you enough, you are the greatest miracle in my life
And again I think you look at me with favor coz I tremble at your word and my spirit is contrite, keep on keeping on

Here is the question again
Why am I mightily used by God?
I look left or right and I see many with learning and greater distinction yet you still pick me even when I'm clueless
What is it that you see in me that I don't see in myself
You make me wanna live again
You my light and my hope of glory
Lord I repeat I'm not worthy of the scars in your hands
You've thought me to be a blessing to somebody on a daily basis
And now the blessed call me blessed coz I lift my head up high and give the world a smile
