I used to wonder (and believe I even asked you) if an aging agnostic would eventually ask, “is this all there is?”The answers to that question could be mind-blowing.
You probably mean atheist and the fact is that most atheists die quite contentedly without ever asking that question. It comes from giving thought to life and belief and faith and knowledge and thinking is a pretty good thing.
I am agnostic however many people, you apparently are among them, who think that agnosticism is a belief or a faith. It is simply the acknowledgement that metaphysical notions are not known. If a genie appeared and offered to give me one wish it would be that everyone in the world become agnostic; there would be agnostic Catholics, agnostic atheists, agnostic Jews, agnostic Muslims, etc. Everyone would retain their belief/faith and they would freely tell others if they wished, spread the word like the Mormons do, but they would understand the difference between belief and knowledge. I like to think that if everyone understood that their belief was not any better or worse than any other belief and that we should be respectful of others’ beliefs the world would be a safer and happier place.
What do I believe? I believe that this life is wonderful. I like to make an analogy that fits well into the Christmas season. I like to think of life as a gift and I know that if I gave someone a gift that was unwrapped and the recipient exclaimed “great gift, Thank you! What else did you get me?” I would think that person was an ingrate. Just in case the analogy escapes you I’ll put it in terms of your belief. God gave you life and you are saying “is this all there is?” I think this life is wonderful and I give thanks for it frequently. I’m not looking forward to something else. If this is it, thank you! If there is more, wow! But my job in this life is to live it fully, to use the gift well and with appreciation.
