It is written that the voice on Sinai was a mighty voice that did not stop.
Many years later this is repeated in much of the hasidic literature, that the voice giving the Law, the Ten Commandments, never stopped.
It is still giving the Law, for ever and ever, for eternity.
Put in another way, there is a very clear message that is always being transmitted.
The thing that has changed is that we are no longer listening.
–Rabbi Adin Steinsaltz
