Mary tell you this because I know God didn't?.
If you go to heaven and God assigns you the role of giving out the Hershey bars at snack time, does that make you divine? Does that make you the source of the Hershey bars?
God, might put me in charge of the chocolate? MMMM. I think I would feel really divine :')
Possibly. The point being that whatever job God gives you to do, whatever power of His He let's you use, the power is His and the Will is His.
