First and foremost: if the search term people use matches text in the meta description, that pleases both Google and potential visitors. As Google is set on serving the best possible answer to a question, it’ll be more inclined to highlight that meta description in the search results. This should entice more people to click on your link as it stands out. Also, the recognition could work. If you are looking for something and according to the meta description, this page seems to be about exactly that, you’ll want to click.
