Do you believe in the power of prayer? What do you think it can do?

I am not a religious person, but I have always believed in 'God' and maintained a personal relationship. I talk to God often and though I don't believe that God necessarily works magic and grants wishes, I do talk about things on my mind and things going on in my life. I do ask for God's guidance and blessings, I even ask for help on occasion when I'm facing or dealing with something that I have a bit of doubt or fear over. I always give thinks to God for everything in my life. I have always felt God's presence in every aspect of my life and I am convinced that God hears, listens to, and even answers prayers...or just provides me the wisdom, knowledge, strength, and even the means to answer them myself. There are many things and many times throughout my life where it is a mystery as to how I ever made it through, got passed it, and moved beyond, its a wonder sometimes that I've gotten to where I am now and have what I have now. There are things that have defied explanation too and I am convinced that God had a hand in it. So yes, I do believe in the power of prayer and I believe in it working and being answered whether the response is yes, no, or just have patience and wait (even if the answer is not exactly what I personally was wanting or expecting... many times it's just as good or even better). God watches over me and takes good care of me. God is a great friend and always has been.
