A single almighty god is just a concept, the same as in a polytheist belief systems. If that is what wakes you up in the morning and puts a smile on your face and persuades you to be a better person then so be it. For those who have stepped out of any holy book's teachings and looked at the history of religions and the human race, they have a whole other picture of what it all means and how it has effected people throughout history.
It all depends on how far you want to take the search for the truth about religion and it's gods or human nature and it's need to believe in a god or gods. If you only limit you search within the pages of the holy books you will find what you are looking for and find a certain comfort within. If you take your search farther in an effort to better see the full context of it all, you may not find what you desire. Absolute truth is not subject to only belief based limitations and unending interpretation of it, but opens the door to examen such things as science and secular humanism.
Not believing in the gods of the holy books does not leave you with a warm fuzzy felling or a belief that there is someone watching over us all. It just puts it all into a clearer perspective and helps those who try to understand humanity and are not afraid of absolute historical truth about the various gods and their believers. It shifts any security or insecurity about humanity and this planet into the hands of humans themselves. Religions have to take that concept of security within yourself away and place in their own various hands. Of course they all say their hands are guided by some god so you can imagine that warm fuzzy feeling of religious security by the way of belief and faith. Depending on what part of the world you were born dictates what religion and which god you attribute those warm fuzzies to and exercise that belief and faith according to your specific religions interpretation of their proprietary holy book.
There are those on this board who do many good things in the name of their god. To them I say good for you, keep it up. It doesn't matter who you attribute your kindness to, just as long as you do it. It also doesn't mean that those who do not believe in a god of the many holy books are not capable of the same level of kindness to their fellow man. They just do it on their own personal accord and not in the name of their cultural anthropology.
