Faith is something one "believes in". It serves a major evolutionary purpose and has been an essential part of human nature since time immemorial. When shared by members of a group, faith strongly supports that group's internal cohesion. It strengthens the group's capacity to to cope with the challenges of a hostile environment. It adds to the group's capacity to compete successfully with other groups animated by different faiths.

There are many demonstrations in the historical record of how this principle has worked in practice. Look, for example, at the efflorescence of human society in the Middle East in the several centuries after the beginning of Islam. Islam's sytem of beliefs provided a unifying force that permitted large numbers of converts to work together to accomplish historical achievements that would not have happened if Islam had never begun. Faith, when shared by large numbers of people, turns a group of aimless, discontented individuals into a purposeful, powerful force.

Faith is a belief in something and it can help strenghen a persons action,but faith isnt fact it is hope.To believe that Faith is realty and truth is a dangerous ideas.
