“The main benefit that is obtained by preaching is by impression made upon the mind in the time of it, and not by an effect that arises afterwards by a remembrance of what was delivered. And though an after-remembrance of what was heard in a sermon is oftentimes very profitable, yet, for the most part, that remembrance is from an impression the words made on the heart in the time of it.”
