Your complaints are not against us, but against G-d.
"The real dividing line in Jewish life today is between those who are happy with the mesora and those unhappy with the mesora. Kabbalat Ol Malchut Shamayim (acceptance of the yoke of G-d’s kingship) demands that we accept the mesora even if we deem ourselves “more enlightened;” otherwise, we – like Nadav and Avihu before us – are worshipping ourselves, and not the Almighty. And isn’t that the ultimate reality of Western man today – self-worship ? If I am unhappy with the Mesora, it is because of something within me that needs rectification. I have to bend to the Torah’s will, and not bend the Torah to suit my will. Those who live with grievances against the Torah must recognize that on some level, as Moshe once said to his flock, “…your complaints are not against us, but against G-d” (Sh’mot 16:8)."
