And all who pray clearly aren't going through the exercise for lack of something better to do. We pray for a reason, perhaps each one of us for a different reason. There is no one way to pray.
Prayer is a very personal thing.
However, we can learn a great deal from the prophets and sages of biblical times. They teach us, for example, that there is special power in praying with a group, in praying at various points in the day, or in reciting Biblical verses or psalms. I tell people who ask me that, if there is one rule to prayer, it is that however you choose to pray you must be willing to put in an effort for your prayer to be answered. Of course, they panicked and cried out to heaven in prayer. But nothing happened.
