The Moon actually revolves on it's own axis in 28 and some fraction of a day, exactly the same time it takes to orbit the Earth. In orbital mechanics, this is called being "tidally locked".
The Moon is returning the favor, by slowing down the Earth's rotation, so that in some few billion years our planet will face the same side of the Moon as well.
