God told His people:
Isaiah 41:15 (TLB)
You shall be a new and sharp-toothed threshing instrument to tear all enemies apart, making chaff of mountains.
Matthew Henry* put it this way:
“He is but an instrument, a tool in God’s hand.”
Matthew Henry’s Complete Commentary on the Whole Bible, 1706
You too can be a tool in God’s tool box. 
*Matthew Henry (1652-1714) was a British minister and popular speaker. He is best known for his verse-by-verse commentary on the Old Testament, the Gospels and Acts.
