If you never used "listen to God" faculty then you can't speak on it, it's just hearsay, not personal experience.
I am speaking from personal experience. I'm a former Christian who once believed that he was experiencing the Holy Spirit. I became a Christian in my late teens, and agreed to suspend disbelief to walk a season in those shoes to see how well they fit, that is, to see if it would begin to make sense. My first congregation had a charismatic pastor that could create a kind of euphoria, which I understood as the Holy Spirit that had been promised would be there. This was while I was away in the military. Upon discharge, I returned to my home state, where I proceeded to try about a half dozen more congregations, all of which were lifeless. It was then that I realized that what I had been feeling was not the Holy Spirit, which would have followed me back to California. Eventually, I realized that the promises were false, and the doctrine never did congeal or make sense, so, like a pair of ill fitting shoes, I stepped out of religion and found humanism - much better fit.
So, I know what people who claim to have a personal relationship with God or who claim to have compelling evidence that God is real are actually experiencing. I know what changes were necessary for me to participate - the suspension of disbelief. That is what is meant by tuning into God - letting down the critical thinking defenses.
Tuning in to the Divine (God) does not imply to not use discrimination, common sense and other given faculties
You just read how that turned out. The evidence that I accumulated after discharge in those lifeless congregations was now being evaluated critically. I was no longer suspending disbelief, and that led me back to atheism. Faith and reason are antithetical. One can make reasoned arguments dependent on faith-based premises as the Scholastics did in the Middle Ages, but they are never sound arguments if the premises aren't established as fact. And one must never train his reasoning faculty on the faith-based belief itself, which reason says to not accept as true until evidenced.
