If I were to sit here and judge I would say that giving isn't based on the bibe because there is a personal benifit for it therefore it is a selfish motive. Now what if an Atheist is charitable? why would an Atheist give... Ask Bill Gates or Angelina Jolie they are both Atheists and they give tons. Besides the ovbious tax write off what is there benifit? well I don't see any...Every Atheist I know is very giving myself included reason? well I can speak for myself in saying I have never taken a tax write off for any donation I have made... I do it because you only get one time around and you want to make sure that you can help make it the best it can be for as many as possible. just my 2 cents
