Oh, you are referring to the whole Biblical idea of God's word being...kind of...encrypted to the unbeliever? Or how secularists can't quite comprehend the things of God? Or how God's Word is nonsensical to the wise and learned? I may have it all wrong.
I think I'd lean more toward the personal Jesus side of things if I could get past the intellectual hurdles.
Yes, or at least I think we're talking about the same thing, I'd probably have to explain it more...if I can it's hard to explain. I'm actually someone who was like memory foam when it came to believing that it was true VS believing it wasn't true. I constantly gave new life to my intellectual doubts, I would believe, then like memory foam I'd reform into the skeptic me again.
So this spiritual discernment concept is hard to explain. Conversion to believing that Christianity is true was not a straight shot for me and it was very long and doubt filled. However the long road gave me an interesting view of spiritual discernment. Let's give my intellectual objections the analogy of noise level, let's call my objections 'Loud' objections. I carried these loud objections with me all over the place, and picked Christian brains if I ran into any, and usually at the end of the conversation the volume of my objections didn't get any louder or quieter, UNLESS a good intellectual point was presented.
However, for argument's sake let's say that your volume knob of intellectual objections is set at 10, well mine was more like 7 because I did have a few things that I found impressive about Christianity (along with the objections). So ok, if you wanted to tweak my intellectual volume knob I wanted to hear something half decent! And my volume knob did get tweaked at times. If someone REALLY made me think the music might even get turned down to a 5.
So this was my thing. I was a Doubting Thomas and I picked brains. And if a half descent point was made I would feel a sort of slight reduction in the loudness of my objections. But again I was like memory foam...give it 2 weeks and I was back at 7.
Now here's where it gets intellectually strange. There is a backstory to this that meditation on Jesus and/or reading the Gospels brought about for me a natural high that existed with no other experience of thought, nothing but meditation on Jesus could produce this natural high for me, this 'Jesus Feeling.' This is kind of like how being in love is an awesome natural high feeling, but it is completely distinct from the awesome natural high feeling you get being around a baby. Both are awesome feelings, but totally different. Well likewise this 'Jesus Feeling' is a natural high that is completely distinct to any other great feeling that I've had in life.
I actually used to use the 'Jesus Feeling' on purpose sometimes when I didn't even feel like 'Going Religious' but I was simply very stressed and I really needed a feel good fix (however it did have the ability to pull me in a keep me for awhile). Ok back to the intellectual strangeness...this 'Jesus Feeling' I got from Jesus meditation or Gospel reading (which pretty much naturally brought on Jesus meditation all by itself as I would read the Gospels) would actually muffle the loudness of my intellectual objections, and the volume knob all the sudden found itself at 1 or 2 for absolutely no logical reason. I would literally sometimes make a confused face and be like, "Huh?? I'm pretty sure I believe now!! Um, yeah I do totally believe now!!"
But the intellectual side of me was puzzled as to why I now suddenly believed...yet my intellectual side (even though it was asking the question) wasn't jumping up and down in protest anymore like it does when the volume is on 7.
But being the hard headed block of memory foam that I was I pulled myself out of those states of belief all the time, this went on for years, I was a seesaw believer. Several times I would sort of try to philosophize with a friend of mine about how this made any sense. How was it that my intellectual objections could get lowered down to a 1 or 2 by doing something that had no intellectual content to it whatsoever??? Then, how could I pull myself out of it...and no longer relate to being in a state of "Volume Knob at 1" anymore, when I was literally just in that state of mind a mere 2 days ago!!?? Lol it really made no logical sense. Nevermind the fact that the entire pursuit for me was an intellectual one!! It was like there were 2 gauges inside of me not just one (gauge #1 the intellectual gauge). And the 2nd gauge was proving to be more powerful.
So I would say that 'Spiritual Discernment' for me is this (logically) bizarre phenomenon where Jesus can significantly muffle the volume of my intellectual objections without a single intellectual point being made. It's almost as if these 'Jesus Feelings' are this invisible blanket of comfort that Jesus places over my body, BUT attached to it is also a head piece that slips over my intellectual doubts. Lol again it is really hard to explain.
I think a guy like me is extremely rare though. People don't tend to seesaw around like I did (I think). Check out C.S. Lewis' conversion story. His path was an intellectual journey. He tells this story about how strange it was that he had been questioning Christianity for awhile...and he found himself on a pleasant drive to the zoo (not in the middle of some intellectual exchange), and then he says that he can't explain it but when the drive started he was not a Christian, but when he reached the zoo he was a Christian. That's probably more in line with how a normal person converts, unlike me lol.
