I really don't think it is an option for most of us, there really is no choice that I can think of when it comes to belief or non belief. On several occasions I have thought it would be nice to believe there is something out there looking after me, and definitely could see the benefit of thinking that. I've never really been able to force myself to believe it though, at the very best all I can really do is acknowledge my own uncertainty and inability to know anything for certainty.
If you had the choice, then it would be beneficial when it comes to thinking about death, about losing loved ones, I could see how it would help with finding purpose and your place - you could create your own God as you see fit. Your God could be all loving, and an eternal hell could be removed from the religion as it has been from some denominations.
I can think of reasons as to why having a God would be a good thing, it would be like having a parent that loves you unconditionally and is looking out for you - there definitely is an appeal to it. There have been several moments in my life, where I had wished to have such comfort to lean upon, and found myself empty handed when looking for it.
One thing to note here, is that a lot of people who believe in God, don't really believe he was some evil entity, they don't even try to justify things written in the bible, they have their own interpretation of God. Hell, it was pretty funny when I had to explain to my own mother that reason why Jesus died for people's sins, she hadn't a clue.. she did not know he died for our sins - despite being a Christian for decades! I think most believers, have their own idea of God going on.
I think for every person out there that believes in a God, they are worshiping their own version. If you think about it, there are billions of different Gods out there, all defined by billions of different people. Some Gods we can see as evil, some are good, some are a bit of both. What is wild, is that some people are so obsessed with their version being the correct version, that they will go out of their way to convince others that their version of God is wrong. It is pretty wild to think about, but then, there is a reason why there are thousands of different denominations. I suppose people feel the more people that agree with their version of God, the more real their version is.
I think it is pretty crazy just how far people take it, just asking Jesus for forgiveness for being a sinner is not good enough anymore, now you have to "know" him in a manner that others "know" him. If you don't understand him in a way that they understand him, then you are doing it all wrong and destined for an eternity in hell
I wonder if pronouncing his name incorrectly is means to an eternity in hell as some people may believe.
