And the Lord said, If your faith was only as great as a grain of mustard seed, you might say to this tree, Be rooted up and planted in the sea; and it would be done.
2 Chronicles 16:7
At that time Hanani the seer came to Asa, king of Judah, and said to him, Because you have put your faith in the king of Aram and not in the Lord your God, the army of the king of Aram has got away out of your hands.
And he said to them, Where is your faith? And fear and wonder overcame them, and they said to one another, Who then is this, who gives orders even to the winds and the water and they do what he says?
