When John Adams said after his wife of 54 years, Abigail, had died…
“I believe in God and in his wisdom and benevolence, and I cannot conceive that such a Being could make such a species as the human merely to live and die on this earth. If I did not believe in a future state, I should believe in no God. This universe, this all, this totality, would appear with all its swelling pomp, a boyish firework.”
Think about that. If there is no afterlife, what could possibly be the purpose of the human race? It can’t lie in the foolishness we do here during our pitiful lives, can it? The wars, the crimes, the hatred even the somewhat nice things like art and music, are they important enough to provide meaning and purpose for all of this? Think of the ridiculous nature of human life. What purpose is there, if not in an afterlife?
I too believe as Adams did, that if there is no afterlife, then I believe not in a god. And if no God, truly, total meaningless.
My two cents.
