The Holy Spirit inhabits people, not churches or buildings (unless they are full of spirit-filled people). I don’t believe that everyone who says they are filled with the HS really are because their lives don’t reflect that. You have to have discernment and a knowledge of the Bible to know the difference.
Yes, what you say is true, however, that makes it now, that we have millions of people, who say they are led by the Holy Spirit, yet they all have differing beliefs...of course, there is discernment and knowledge of the Bible, to at least figure out for yourself, if you believe that someone is led by the Holy Spirit...but as we have seen, just on this thread alone, time and time again, even with Biblical knowledge, many wind up interpreting the very same Scriptural verses in very different ways...so there again, they cannot all be led by the Holy Spirit, and the way one person interprets Biblical Scripture differs, sometimes in a small way, sometimes in a grand way, from one person to the next...
So, it can and does happen, that someone can say they are led by the Holy Spirit, and one person, depending on how they interpret Scriptures, will not believe it, and then another person, interpreting Scriptures differently will believe it...
