I've read your post a few times, and it still makes no sense to me, really. To be honest, it was exactly this kind of thinking that helped me to realise that I wouldn't ever believe.
"Willing it to be so" obviously makes sense to you in some way, but it doesn't sound much like faith or belief to me at all. Rather more like an elaborate pretence to the self, a conscious choice to suspend disbelief. Fair enough if it works for you, but it was all too "Emperor's New Clothes" for my liking, but each to their own.
There was a time when I desperately wanted to believe, but that was before I knew very much about Christianity. The more I learned, the less sense it made.
I guess I might have been more persuaded to carry on with the make-believe if I had actually seen it as something worth aspiring to, but ultimately, I didn't share your view that Christianity had any of the answers. To you, I get that the world looks bleak when God is taken away. For me, it doesn't really look any different. I tried a number of different churches, and from what I have observed, Christians are every bit as flawed as the rest of us. I found no evidence of any unique wisdom, insight or compassion. No higher morals. No more courage or honesty. No less pettiness. No less bigotry. No more peace. Just a belief in some Christians- certainly not all - that they were right and that everyone else was wrong. I found that side of it rather arrogant tbh, and terribly lacking in humility. I also saw a great deal of hypocrisy.
On top of all that, there was the issue of the Christian God, who is portrayed in the Bible as a loving father, but also comes across at times as capricious, vengeful or even cruel. There were a lot of things that didn't accord with my idea of a loving parent, and I never found a Christian who could provide any convincing explanation of this. Just platitudes, generally. I couldn't paper over the inconsistencies and the cognitive dissonance was too much for me personally.
I did come across some amazing Christians to be fair, who were inspired by their faith to serve others and do some incredible things. But I have seen equally amazing people of other faiths and none. So that alone didn't really carry much weight for me.
Perhaps I could have carried on going through the motions of pretending to believe. Perhaps, had I carried on for long enough, I might even have almost persuaded myself, if I had "really chosen to do so". At least, perhaps, I could have done a better job of burying my doubts and pushing them away.
However, having spent a few years exploring that avenue, I suppose I didn't make the choice to keep playing that game because I saw no real reason to choose it. I liked the sense of community that the church had to offer. I liked the singing and I liked the ritual. But ultimately, I didn't find any value in it beyond that, and I felt that there were other more honest ways of me creating those things in my life.
I have every respect for people who find comfort or inspiration in their faith, and I am genuinely glad that they have that in their lives. However, I really struggle to stay patient with those who seek to push their faith on to others, with those who are convinced that they have found the one true path, or with those who believe that they somehow have the moral high ground, because for me, those attitudes represent the very worst of Christianity.
