I think that doing ANY mitzvah makes us more worthy of being answered affirmatively by Hashem. It happens that I am greatly troubled by people who talk during the davening and laining. I cannot focus on my own davening, and in my shul I am the “wicked witch” (yeah, THAT lady whom we all knew from our own childhood) who is always going outside to shush the young men who are standing outside the ezras nashim, talking naarishkeit.
People do not realize what a chutzpah it is to be asking the R”SO for our bakoshos, when we don’t even have the respect for Him that we would show a famous person who is talking to us. WHY would we think Hashem would be predisposed to saying “yes” when we didn’t even have the courtesy to refrain from extraneous (and dare I say, stupid)irrelevant conversation while we are supposed to be engaged in conversation with HIM?
