I know it's different for different people. But as it turned out for me, I first heard from God and then went to the scriptures. Which, in doing so the one confirmed the Other, and vice versa.
Unless I am missing your point, it seems you are wanting to go from an objective, verifiable way to knowing God's mind through study of the written word to a subjective, non-provable and non-biblical way.
If your way is the best way, then why throughout the NT were men
TAUGHT through
WORDS God's will and why epistles written in
WORDS sent to various congregations? Obviously those words could be read/heard and understood correctly as they were intended to be understood, Ephesians 3:4; Acts of the Apostles 17:11. In Acts 8, the way the eunuch was given understanding (Acts of the Apostles 8:30-31) was
NOT by the Spirit miraculously illuminating the eunuch's understand apart from the word but by the Spirit sending Phillip to preach
WORDS to the eunuch which the eunuch understood correctly.
Those who
CLAIM (for they cannot provide any proof whatsoever) they get direct, Divine, miraculous revelation of words from God/Holy Spirit
contradict each other all the time. When they are not busy contradicting each other, they are contradicting the written word of the Holy Spirit which is something the Holy Spirit would never do, the Holy Spirit never contradicts Himself in giving a confusing, contradicting message (1 Corinthians 14:33).
If one cannot read the written word and understand it's meaning correctly as God intended it to be understood, then how can those who
CLAIM they receive direct revelations from God/Holy Spirit be certain they correctly understood those revelatory words as God intended them to be understood?
