Due to time constraints I'm going to focus on just parts of your post.
Actually intuition can be quite reliable as a basis for believing what we know about something because it’s not an unsupported feeling or subjective opinion but based on experience and constantly assessing and testing that experience which allows us to form pretty strong beliefs about what’s going on.
What you're describing as intuition others would call bias, and people rely upon this intuition/bias because unsurprisingly it tends to confirm their preexisting beliefs. So yes, it seems as if intuition is a reliable means of judging what's true, when in fact it's probably the exact opposite, it's a deep-seated means of avoiding what's true, or at least avoiding admitting that one doesn't know what's true.
Now we as humans tend to remember the times when our intuition was right, and forget all the times when our intuition was wrong. And then voila, our view of intuition becomes self-reinforcing. We intuitively think that our intuition is reliable.
It's not.
For example our intuition tells us that the physical world is really true (our reality) as we experience and we are not living in some simulation experiment or part of a multiverse.
This is where you and I are completely different, I make no such assumption. I am in fact an epistemological solipsist. I try very hard not to make unnecessary assumptions, although in the quest to have meaningful conversations with others a certain degree of assumption is unavoidable. However, I try to keep it to a minimum.
My point...stop relying on your intuition. Stop letting it be self-reinforcing. Always question it, and when doing so always be careful to avoid confirmation bias. This doesn't mean stop being a Christian, it simply means that you should differentiate between what you can know to be true, and what you've simply been conditioned to believe is true.
If you can do that. If you can stop deceiving yourself about what you "
know", then you may have a whole different perspective on what it means to walk by faith. It doesn't mean to self-deceive yourself.
Anyway, enough preaching. You're smart enough to figure this out on your own, so forget that I said anything.
