But I'm so little

I am constantly being reminded that God wants to use us to do his will. It may be in my personal life that he tells me to do something or a reminder in the book I am currently reading but the reminder is the same. There is always a character that thinks "God can't use me I'm too small" whether it be physical stature or position in society. Then God steps in and uses them to do something great and once again I am reminded it doesn't matter how big you are but whether or not your willing to be used.
