The blessing that is recited on the occasion of reading from the Torah scrolls, “Blessed art Thou . . . who gives us the Torah,” is in the present tense, “gives,” not the past, “gave.”
The Torah itself is always forming and expanding.
It is a constant growth.
The event at Mount Sinai is an ongoing Revelation that repeats itself whenever one studies Torah.
One may not be aware of standing before the Holy Mountain, but God is still uttering the Ten Commandments.
Even if one does not hear them, the standing itself, in awe and terror, is enough to establish the correct relationship to Torah.
The realization of this is, in turn, something acquired by study.
