I’d try driving thru the express lane at McDonalds.
Seriously, it can take allot of time, and earnest soul searching (it did for me). It costs nothing though, so you lose nothing while you search.
I’m aware of the time it takes. But sane people do come to a point when it becomes pretty obvious that the efforts are futile.
Atheists don’t wish there was no God. They just don’t see Him, no matter what efforts are put in to believe. It gets tiring after a while, and giving up is the most sane thing to do. Betraying one’s own sanity is akin to mental adultery.
