What does 2 Kings 4:31 mean?

Gehazi went ahead and laid the staff on the boy's face, but nothing happened. The boy didn't move or make a sound. Gehazi went back to meet Elisha and said, 'The boy hasn't woken up.' 2 Kings 4:31 - Modern Text Bible

(The staff alone doesn't bring the boy back. This shows that God's power isn't in objects, but in his direct action.)
