life changing prayer

so last night at revolution we talked about hannah and her dangerous prayer... it was a great message it was all about the power of God and that He can do anything.... if we pray for the right thing with our whole heart and we put the will of God before ours and if we know that His plans are bigger than we can ever imagine.....then we know that we are praying a dangerous/ risky/ life changeing prayer and that it can change the world....the effects can live on longer than you do...i dont know if you can get more hopefilled than that....
