Most people pray out of necessity. And the words that are used in their prayer are more or less repetitive.  There is no life in their prayers. The prayers are filled with personal requests. It will have materialistic needs or wants and also lots of request to bless.

I believe a prayer will be sincere and effective and God answering when it is prayed intentionally.  The intention is that it will be heard by God and not for one's emotional satisfaction.  The intention is to intercede for others.
