Our prayers are a reflection of ourselves

After vespers today one of the Sisters told me that she doesn't understand the concluding prayer. It is in Italian and it says something about asking God to look kindly on our questions, and so on and so forth. I thought she was joking but then when I looked at her again she was really serious. What are the questions that we are asking God to answer?
I will not attempt to answer. But her questioning led me to another thought. In that same concluding prayer we are asking God to look "kindly". But He is a God of kindness, so surely there is no need to remind Him about that!
I remember that when I was a student I had a theology professor who always scrutinized our spontaneous prayers. He always found fault on one or two expressions, saying that it's vague and it doesn't make sense, or that it is redundant, etc. In the end we were almost afraid to formulate spontaneous prayers since we didn't want them to be massacred.
I may sound heretic but I guess that when we pray, it is really an expression of ourselves. Let's get back to that example earlier asking God to look kindly. It is a reminder to me that God is a kind God, that whatever be His response to my prayer, it doesn't diminish His kindness.
More than revealing God to us, prayer reveals us to ourselves.
Is God jealous? I don't think so because I also believe that God is happier when we become true to ourselves because it is in this authenticity that we finally find Him.
