“Evidence in the form of the manifestations of the Spirit of Truth to me following prayer and sincere seeking. I am satisfied.”
None of that is factual evidence. You made a claim of truth, which requires facts, evidence and logic - none of which you can provide.
Instead, you gave us your opinion and feelings - concerning a demonic manifestation.
This falls short of supporting your claims.
I quote Paul regarding gaining spiritual knowledge:
“But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.”
“For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.” (1 Corinthians, 2:10-11)
However, in terms of ‘factual logic’, I would point to the witnesses of the Book of Mormon whose testimonies can be read here:
