There is an important principal of our faith that many people don't think about. Hashem created us because that was, kviyachol, His will. NOTHING compelled Him to do so. The Goyim served idols because they wanted to manipulate the various gods to do their will. But we have none of that. לא באלה חלק יעקב. The Jewish people know that we can't "manipulate" Hashem into doing anything because there is nothing that can force Him.
So we have to remember when we daven that we are not demanding. We are not ever saying [as some do] "Either you give me what I want OR ELSE....." We are merely asking and Hashem will respond based on His will and not because he HAS to do anything.
