It’s a thing most true atheists have read religious texts. I personally have read the Bible multiple times cover to cover. I’ve also read to the Quran and I’ching. The thing that’s hardest to understand about atheism for most theists I’ve found personally. Is that it’s not an alternative to faith and belief it’s t the e absence of. It’s not I believe in Y instead of X it’s I just didn’t believe in X .

But yes I’d advise any theists of any religion. Read your religious text, but don’t let someone else tell you what it means what it’s trying to say. Read what it actually says there on the page and come to your own conclusions
