Please excuse me, this one will be done off the cuff and by memory (and it might look like nooseisko wrote it). I saw this in the Lekach Tov on ROsh Hashana.
The shofar is one of our greatest weapons against our prosecutor. Yet when Rosh Hashana falls out on Shabbos, as it does this year, we don’t blow on Shabbos.
Why don’t we blow when it falls on Shabbos. The Gemarra tells us that we are afraid that there will be an unskilled ba’al tokeah, who might end up carrying his Shofar accidentally, when he needs to find out how to blow. Lets look at this, the ENTIRE KLAL YISROEL needs to put down the shofar and face the full wrath of the Yetzer Hara prosecuting us without our main weapon BECAUSE ONE OR TWO YOKELS MIGHT ACCIDENTALLY CARRY A SHOFAR IN PUBLIC?!?
In the words of a hotheaded American Tennis Player: YOU CANNOT BE SERIOUS!!
The answer is extremely simple and equally as terrifying. We only think this is a question because we do not know how bad aveiros are. We put down the Shofar because it will be better for ganz Klal Yisroel to be without the Shofar than to have 1 or 2 averos b’shogeg added against us.
As we approach Rosh Hashana, Aseres Y’Mei Teshuva and Yom Kippor. We must heed this mussar as to how bad averos are and how far we go to avoid them. If this is how far we extend ourselves to prevent an aveira b’shogeg, imagine how horrible an aveira b’meizid is.
