@just me it's with some hesitation that I'm making this comment, but I'll have a go.
It seems to me that you feel you have a very deep commitment to Christ. I think the problem you are facing is that you are bringing yourself to these discussions in a way that can't appeal to dominant intuitives, and that is so sad because you very likely have valuable things to say. It's as though you are trying to get through a wall that has no door in it, but you keep on knocking as though there was one. Maybe you need to think about going around the wall instead? To put it explicitly, Ni dominant people build very complex inner models of the world. With something as profound as a spiritual perspective they will have spent a lot of time and energy on this - they won't modify their views quickly and easily when new input is at variance with their insight and will react defensively if pushed too hard. I know this is the way I am - perhaps you are like this yourself too?
What dominant Ni's do very well – again, this is what I do - is to suspend judgement, listen, express their own ideas non-judgementally, clarify through discussion, throw in some humour, and over time all these new ideas help their inner vision to grow, often in ways they never expected. It is a rare privilege to find a group of people like we have in this forum who see and think about the world in our own kind of way. At our best we tread lightly on other people's visions when we are on their territory and treat others as guests when they are on our own.
When I look through this thread I can see almost as many views on the topic of original sin as people who have posted, and they all seem to have been listened to courteously and considerately in the main. My own views are different from those of many others in the forum on religious topics - this is great because I can learn so much from what they bring to any discussion, and I hope others can gain something from me. I'm new to this particular the thread and in just a couple of days it has given me much food for thought and a far better feel for the topic than I had before.
