There is a Ramban in the end of this week’s Parsha (Bo) that elaborates on this point – of davening out loud. ???? ??? ???? ?????? ????? ???. Look it up – it’s the last piece. He sais that this is the reason for creation!
Besides for this reason, I heard from R. Miller Ztz”l, that when we do mitzvohs and especially when it comes to davening – talking to HaShem, we do it with enthusiasm. When talking to a friend or doing business, then it’s the time to tone down. That in effect puts things in their proper place. When Kohanim went about their ways in the Bais HaMikdash, the did it with vivaciousness and pomp, as ?????? say ????? ??? ?????. That’s why originally they would run onto the ???? vying for the ???? of the ??????.
Nowdays, R. Miller ztz”l notes, we find even Torah oriented Yidden who find davening boring. Upon entering they pick out a bunch of seforim to look into, some publications, and then maybe a small siddur too. The davening as a whole is spent between on sefer and the next, with some mumbling in between. Is this Kavod HaShem? We’re talking about Talmidei Chachomim on Shabbos. How much worse for businessmen and during the week. ???? <click> ???? <send> ???? <inbox> ????? <outbox>. Disgusting! Is this all the attention we afford our creator. Then at the towards the conclusion of davening, the talis & tefilin long wrapped up, three feet out the door already waiting for him to finish and be done already! I once heard about an ancient custom by the Yekkies, if one removed his Tefilin before the very end of davening (being impatient) the Kehilla would fine him.
The sport fans root their heros loudly, let us too root for HaSHem LOUDLY with fanfare.
