If my own past experience (as an atheist, agnostic, wanderer, undecider) is an indication, yes, you will still be welcome here. Just don't be combative or ridiculing, and follow the rules as best you can, and you should be fine.
I will add--and I don't expect a response on this, and you probably shouldn't give one in public anyway--that you are perhaps, maybe, possibly dealing with an issue that I have dealt with a long while (like 20 years), so let me just say something. If you find yourself constantly changing your mind, even if it seems perfectly rational and sensible and right each time, even if it seems like a normal and proper response, yet you keep changing your mind about significant decisions and important parts of your life, consider seeking any and all help that you can. Talking with someone/some people may be enough, or it may not. There are other options; it's good to know what those options are. I don't know the likelihood of cures, or learning to manage things, but if you struggle with anything at all like what I do, it's frustrating, and decades of going through the grind of it will most likely leave you about ready to check out. If there is indeed an issue, don't wait, and don't rely on the hope or expectation or thought that it will just automatically get better. It may, or it may not. My advice would be to not take the chance.
But again, don't feel run off or like you can't participate--I wish you the best, and I hope you find your way through to ... wherever/whatever.
Justin brings to light what many Christians do struggle with. Many of us here would be lying if we didn't have "waves" of at least quasi atheism (agnostic stuff) go through us at times. Some stronger than others, some not as much. Then there are those who are strongholds who never doubt no matter what.
In my personal walk, I've never been an atheist. I will say there have been bouts at times where I would have called myself a "mostly Christian with streaks of agnostic" where I would say that my belief in Christianity would have been there, but relaxed and open ended (sort of like a parable). For instance, thinking of Adam and Eve as a parable of sorts, rather than specific people of Adam and Eve. Comparing the serpent as temptation that slithers into your life. etc. Leaving creation undefined. Things like that.
I would only suggest and advise anybody who struggles with full atheism (or bouts) to hang on and never give up trying to seek answers.
Sometimes God will speak to you in ways you never imagined.
Example, on my farm we raise heritage bourbon red turkeys. (you should google a photo of them, they are really neat). These would be the types of turkeys that the Native Americans ate and not our gross corporate raised turkeys today. Anyway, we incubate the eggs artificially in an incubator. I'm going to tell you something - you would NOT BELIEVE how difficult this is compared to chickens.
In order to hatch these things, you need fresh air, 90% (yes 90% HUMIDITY with fresh air!!!!!!) at a constant perfect temperature. I had to build an incubator that was completely insulated to preserve heat, yet build a fresh air heater and air expeller (for the incubator part). This way it will dump out old air but bring in fresh humid air at time intervals. Otherwise they do not hatch!!!
God created Bourbon Red Turkeys to be able to somehow incubate the eggs, provide just the right humidity, and air circulation. The turkeys perfectly will incubate the eggs themselves.
(just fyi, broody turkeys do not always keep laying (as they don't eat as much because they sit on the eggs), so in order to maximize laying potential, you have to take the eggs.)
Anyhow my point is, as a man I had an incredibly difficult time understanding that in this natural world exists things that are incredibly hard (yet simple enough concept) for man to re-create. How did these survive in the wild is beyond me.
Now chickens, that's child's play.
They are easy to incubate/hatch.
While I am not saying that stuff to try to convince you from my experience, I'm just suggesting to allow yourself the opportunity to still try to recognize God in stuff. He may "speak" to you through certain experiences. The turkey hatching was mine as I scratched my head for years just getting the incubator right. (it was CRAZY!)
Things happen in life where you may give faith another try. By you saying you wanted to stay on the forum, that is a good sign that you are allowing your own intellect the opportunity to listen to the other side of the story and prove itself wrong.
I'm on the EO forum to do that as well. I've always said I could be wrong and may one day rejoin the church. I recognize my own fallible mind in this manner. I could be wrong about anything I fight so much about (yes, icons, father/master, Constantine etc., and a few other church practices). If I don't recognize my fallibility and that "I" can be wrong, I would believe that I am only being ridiculous and stubborn.
Faith for me can't be blind. It can be mysterious at times and there are a lot of things I can't understand, but over all for me faith has to be backed up strongly. There are many other things that speak faith to me than Turkeys btw. Farming in general has brought me closer to God, awkwardly as much as prayer. Watching things like grass grow from no where, rain watering the grass, goats eating the grass, goats kidding, 1 goat nurses the babies of 2 goats - while I can take the milk from the other giving my family milk, butter, cheese, cream, etc. Just amazing. Perfect order of things. Goats not only provide for their own, but enough to provide for my family while the grass provides for it all, and the rain/sun provides for the grass (as well as decomposing nutrient including goat droppings). It's just this perfect and beautiful balance. A harmony - not just random notes...
It is also incredibly peaceful to watch the herd work in this manner.... those quiet times... I can't describe the overwhelming faith I feel in those moments.
