Rav Yitzchok Sorotzkin says, “We are living in a time where we need extra protection from Hashem, and it appears that this protection is lacking. It seems that the reason for this is because there is talking in Shul during Davening. Chazal teach us that our Shuls are our protection from our enemies. Our Shuls are where the Shechinah is found, and this Shechinah is what protects us. When we talk in Shul we chase the Shechinah away! The Noda B’Yehuda writes in his Drashah for Chanukah, there is no greater rebellion to Hashem than to talk in Shul during Davening! It is the biggest disgrace we can do to Hashem! It says in Shulchan Aruch that the Aveirah is too great for Hashem to hold! It causes the Shechinah to leave the Shul! Can you imagine going to your friend’s house and chasing him out of his house?! Is there any worse thing than going into Hashem’s House, the Shul, and chasing Hashem out of His House?!? This is a tremendous rebellion! The Zohar says that it shows he is a Kofer B’Ikar, a heretic and a deviant! The talker doesn’t realize that Hashem is right there! How can you speak right in the presence of Hashem and push Him to the side?? If we can strengthen ourselves with this, we will merit the Protection of Hashem for us and all of Klal Yisroel, that our Tzaros will stop, our suffering and distress will end, and we will be Zocheh to greet Moshiach B’karov!!!”
