When we take specific questions to the Lord, or ask for verification of a specific doctrine, and He sends the tingling, burning, witness that it is true, then we have, on that point, been blessed to have accessed absolute truth.
I have received that burning in response to direct questions that have confirmed to me many truths with regard to the restored gospel. Among them; Heavenly Father lives, is real, and loves us perfectly. He is motivated in all he does by a love for his children, and desires for them to be saved. Jesus lived, died and rose again. He loves us and desires like the Father, that we be saved and dwell with them eternally. Joseph Smith was a good, honorable and moral man. The doctrine of eternal families and the sealing power is true....... There are many more but these suffice for this post.
The beauty of verification by God , though his Holy Spirit, is that one of the functions of the Holy Spirit is that it cleanses you. I think that is why it is manifested as a burning, a purifier, a refiner. In order to escape the problems with reliance on faulty human logic and the week arm of the flesh, (or the inescapable and absolute truth that all humans are flawed, and thus all flesh reliant methodologies are subject to those flaws,) if God would have us know truth absolutely, He must provide a way so we can overcome those flaws. That way is the Holy Spirit. Revelation from the Holy Ghost is more than just a perfect God verifying truth with a perfect power that only He can control. It includes a process whereby He sanctifies the humble recipient, and thus overcomes the flaws of the flesh, making them of no effect on that point, and allowing imperfect humans, to know truth absolutely and to be able to rely upon that absolute truth forever!
