Just received an e-mail from an organization dedicated to Rav Miller. Rabbi Miller said to honor Hashem one must develop a sense of thankfulness to parents for providing us and teachers for transmitting Torah to us. This, according to the rabbi, trains a person to be thankful to Hashem. Apparently one needs to be ingrained/conditioned by their environment to be gracious and thankful before they can understand or even attempt the need to thank Hashem and give him due praise.
Hashem indeed did not have to create the world for His sake nor does He need our praises for his sake. Developing an appreciation for Hashem surely teaches us to have more appreciation for our fellow man (Rav Miller would likely define fellow man differently than I do) making earth a better place (Tikkum Olam). We thus give G-d his praise. It is behavior that moral and ethical humans do whether or not the recipient needs it or not.
I suggest we all begin appreciating each and everyone we know. Maybe then this concept of giving Hashem praise will make more sense. Thank mom and dad immediately!
