The Mesilas Yesharim says that when we love someone like a father, we want to do extra for him to please him even if we don’t get a reward for it. We love Hashem, who is a father to us, so we want to do extra to please him and specially in the ten days of teshuva drinking chalav yisroel, as we want to be judged not by hair splitting, exactly what we deserve.
