However, for the atheist, I have a few ideas I would like you to consider. Does love exist? There is no tangible way to prove the existence of love. Yet we have all felt love, all seen it. One does not doubt a mother's love for a child. Yet we cannot prove that love in a rational way. Acts attributed to a mother's love can just as easily be attributed to the instinctual need to ensure the survival of the species, even when an act of love can have a negative effect on one's own ability to survive.
Despite this, we still believe that love is a real thing.
The connection to God is similar to the feeling of love. As many religions would say, God is Love. While we may not be able to prove God in a scientific way, those who are moved by religion can feel God in a way that is beyond rational understanding.
People are more than just rational beings. We are capable of the abstract. Art, music, even the creative thought we use to solve scientific problems, these derive from some irrational part of the human mind. If we can accept that there is more to the world than simply what is reasoned and rational, then an abstract God may not be much of a stretch of the imagination.
I will admit there have been shortcomings in organized religions. Terrible things have been carried out in the name of religion, be it the Inquisition, Al Qaeda's reign of terror, or any number of atrocities that atheists are sure to list. Religious organizations have slowed or stopped the flow of scientific or progressive ideas. men can easily use the name of God behave according to their own will.
I also admit that a rational and enlightened person can be morally upstanding without the threat of retribution from a supernatural authority figure. However, these items are beside the point.
I do not believe in God because someone told me to. I do not believe in God for want of Heaven or fear of Hell. I believe in God because I have felt God, and I have seen His Work in my life. So have billions of others. Now the belief of others is no reason to believe something yourself. All that I ask is that you stop for a moment, quiet your mind, and see what you feel. If you are searching for meaning, for something more than the shortcomings of the world you can see, taste, feel, smell, and hear, then open your heart to something greater than yourself.
