People pray to feel secured. They believe God will cure their health problems, mental problems and financial problems. They feel God will take care of their miseries. This type of faith will give a free mind and help to focus better. But they have forgotten the goal or moral of "The God". "Karma" is the main thing behind "The God" It is nothing but cause and effect. If I am "The God" to make people understand "karma" is tough. People understand "Law of motion", for every action there will be reaction. But they dont apply it in their life.
