Three things, ShadowBoxer.
First, you have to stop acting like you're not part of a religion. That's simply not true. You believe Jesus was the Son of God and the Bible to be the Word of God, which makes you a Christian. You don't necessarily have to identify with any specific denomination - you could be an Independent Christian - but that still makes you a Christian and part of an overall religion nonetheless.
Second, you've essentially just repeated everything we've discussed previously. To which my response would still be the same: the human mind is extremely susceptible to illusion. That goes for all of us, not just the religious people. There's a great video by Dawkins and Harris on this topic but I can't find it on the moment, so I'll leave you off with an analogy.
People often say the same thing about cancer survivors. They say it's a miracle if they or someone they know has survived through the horror of cancer. But let's think about that for a second. The probability for the survival of certain cancers is about 5%. That means 1 out of 20 patients would survive. Sure, it may be a miracle for that one patient who prayed to God and let Jesus in his heart...until you take into account the majority of those 19 patients probably did the same, yet you won't see a headline on news titled "19/20 pray to God, then die" because that's just in poor taste. Same thing applies to cases like the Holocaust, where the surviving Jews were deemed as a miracle and example of God's grace...forgetting two thirds of them were wiped out. That's just the brilliance the human mind at work, trained to isolate the positives from the negatives as a means of creating hope for going forward (and that's not necessarily always a bad thing).
The point being: When you take in account the grander context and realize the randomness of the universe., you begin to realize the chaotic randomness that happens daily in our lives. Every time you feel like God reached out to you, there were probably 10 or 20 people in your same shoes whose prayers weren't answered.
Finally, the fact you're happier as a Christian has nothing to do with the validity of the claims made by religion. You're not arguing why Christianity is true; you're arguing why it's useful. It's an important distinction to make. And to an extent, you're very right. Studies show that the average Christian, given all other factors being equal, is much happier than the average atheist. But that still doesn't add any validity to the factual claims made by Christianity. At best, it shows beliefs have their own evolutionary advantages and the human brain is reliant on it to a certain amount. It may be in our nature, but that by itself doesn't make it true.
Seriously in studies, those of higher religious beliefs have shown much higher levels of dopamine in their brain than non believers.
All have sinned, all fall short as they say) full control over this through meditation and prayer and it's been pretty wonderful. Plus some things are happening that I feel have been kind of preordained, but still falling into place, and it's just a crazy awesome roller coaster man.
