Of course you do. But even if you would hypothetically allow that it is true, it didn’t break any natural laws – there was a storm, a man in a boat said something during the storm, after a (very short) while, the storm was over. It was just a coincidence. (It became completely calm and they had to row all the way back, because of their lack of faith. 
)
Pretty much everything you said in the whole reply, since you deny the miraculous nature of providence. You have no choice but to frame it that way.
