What Obligates You To Appreciate Hashem?

Despite the fact that what our parents did for us was motivated by their own feelings, we are obligated to be grateful to them. And if we are obligated to show gratitude toward a father and a mother, then how much more are we obligated to show gratitude to Hashem, the Source of all good. We are not His children physically and not part of His personality. Thus, He is not motivated by any of the weaknesses of nature that parents have. — Ohr Avigdor Shaar Avodas Elokim
