Contrary to what atheists or agnostics think, the value of religion is not in determining whether God exists or not. We will never know for sure. The value of any religion is in some similar to that of the electrons. No one can see or smell electrons, yet the entire world of electricity and electronics is based on that concept. The same applies to religion – it’s how your religious or other beliefs shape you, your behavior and your lifestyle that matters – not whether your God exists or not.
Do you use your religion to make sure you don’t violate the law, because you are afraid that your God will punish you? Good for you. Whether your fear of God is rational or not, the end result is good for you and for others around you.
Do you believe in karma and participate in various charity activities, because you believe that God will be generous to those who are generous to others? Who cares if God actually works that way. As long as your belief leads you to doing these good things – all the more power to you.
On the other hand, if you believe that your God drives you toward any type of unproductive revenge, murder, suicide, torture, etc… that’s a different story. It doesn’t make your God bad. It most likely makes you bad for thinking so lowly of God.
To all the non-believers – God must be perceived not as a living being or an object but as a concept. Perhaps that’s the reason that the major ancient religions prohibited any depictions of god, such as painting and statutes that would attempt to portray God. Because any such depiction undermines the value of the concept itself.
Once you are able to accept and embrace it, you won’t worry about the existence of God, because it won’t matter.
