Cephus
Relentlessly Rational
I do not believe I was mistaken. It is possible that you are mistaken.
It is certainly possible, but how do we make that determination? We look for evidence and we evaluate the claims made critically and objectively. Which one do you think is going to stand up?
I believe I know that I am not delusional.
How would you know that? How do you test it? Do you think crazy people are aware that they are crazy?
I believe all things turned out to be true so there was no deception.
No, that just means that you were deceived.
Here it is for you to evaluate:
The Holy Spirit came to me on Saturday night saying that they slipped something in. On that Sunday morning the confession was being given as usual but at the end "in the name of Jesus" was slipped in when it never had been before.
This is something that Jesus took exception to because it suggested that He was responsible for a person sinning when in fact He is the savior from sin.
That's called confirmation bias. Going by your description here, the prediction was incredibly vague. It doesn't say what will be slipped in, when it will be slipped in, who will slip it in or anything else. Eventually, somewhere, something will happen that will confirm your preconceived notions and you can proclaim that it was right. If it never happens, you never stop looking and can never conclude that it was wrong, it just hadn't happened yet. These predictions never take the form of "on this date at this time, this specific unexpected thing that cannot be random chance will happen", such that you can reveal this to others and we can all see if this event actually takes place. These predictions are not at all impressive because it's up to your personal interpretation to decide if it happens and we have to trust that you're telling the truth about the prediction in the first place.
