Their are millions of peoples all around the world who believe in one God or another Christian and non Christian.
All of them pray to their Gods for this, that, and the other. By far the majority never hear God answer them audibly ,however most assume he answers their prayers or not , by what transcribes next in their lives.
You pray for what is right according to God and he answers your prayers ,otherwise your prayers are not answered .
Those few who who do claim to hear the voice of God audibly are usually found to have mental problems ,either physical or emotional.
If you do good you will be rewarded either now or in the hereafter , if you do bad you will feel the wrath of god and his judgments.
I equate this with superstitious beliefs ,what do you think ?
