I recently realized that if I was an atheist I would have no purpose in living because what would be the point?
The point would be to learn all that you could or wanted to learn, and better yourself, using means that are morally and ethically acceptable, and hopefully in doing so, you better the lives of those around you, or at the very least you'd make their lives more pleasant, and you'd want to have fun and enjoy yourself as well.
I have lots of purposes in life. I still would like to write a symphony, a screen-play, a novel and I'm currently reviewing Shakespeare's works to select one and re-write as a modern story (or screen-play). Over a year ago I was producing musical groups and mixing soundtracks.
I don't despicable trash like Vishna or Allah, or the grotesque moron Yahweh to do any of that. And while I don't think I consider Jesus to be despicable, he was a bumbling idiot that talked in circles, and having gotten rid of him has greatly improved my life.
At least if you believe in heaven you can believe that you will be able to see the changes you have made in your lifetime.
I don't need heaven for that, and the rambling moron Jesus never once mentions heaven. He did say that you could achieve eternal life, if you follow the Commandments, and sell everything you have and give it to the poor. He also said you'd have to be more righteous than a Pharisee, which means you'd have to comply with all 613 ridiculous laws of the
Mitzvot.
Have fun with that.
If you do not believe in heaven then what is the point in doing anything in your lifetime (or living for that matter) if you believe that you will not even be able to view the results of your work over time?
Well, you don't get review anything. What you get to do is put on a white tupa and sing, "Holy, Holy, Holy is the Lamb!" for all eternity so you wouldn't have time to do anything else, and I must say, that doesn't strike me as the least bit fun singing for all eternity to an idiot.
