I do not ask God for things. The very reason I do not ask is the reason he commands us to do so. Jesus tells us to ask, and we will receive. That word really has a closer context to the word "beg". Beg and you will receive. The reason I do not ask God for anything is highlighted by true context of the word in begging.
I do not ask anyone for much of anything, and I have always thought it was a humble reasoning. I refuse to make God into my cosmic Santa Claus, and I don't want to impose even the smallest thing on anyone.
Sounds and even feels a bit humble, but I think the true reason under it all is not so noble.
I do not ask for things because I do not like being dependent on anyone else.
I do not want to be a beggar at any level; no matter how small. The very act of asking is an admittance of insufficiency, and I do no like asking people for anything. I don't ask God for anything because, truthfully, I don't want to be so insufficient that I need to ask or beg for anything.
God commands us to ask because he knows it is so against our nature, and we need to be dependent on Him.
We are all beggars in need Only some of us swallow our pride enough to beg.
