Not Making a Difference?

As the movie, Harry Potter and the Prisoner of Azkaban, comes to a close and Harry is thinking about some of his eforts in previous portions of the movie, Harry tells Professor Lupin that "none of it made any difference." Professor Lupin then explains to Harry that his efforts did indeed make a difference.

Often in our lives we expend effort to assist someone or to accomplish a good goal, and these efforts, from our perspective, indeed look like they are not making a difference. But the truth is, and will eventually come to light, we are indeed making a difference. Someday the good Lord will reveal the beautiful tapestry He is working on. a tapestry that includes all the little threads our efforts - big, small, or in between - are part of.
