You are so far off I hardly know where to begin.
Baloney. Heb 1:1-2 merely adds Jesus Christ to the historic list of prophets speaking to us - it doesn't spell the cessation of prophecy or God's voice. That's called eisegesis.
Which inscripturated words were NOT solid food! See 1 Cor 3:1-2, and Heb 5:11-14, and (1Pet 2:2). Chrysostom remarked that not even “Scripture hath anywhere discoursed to us of these things" (Chrysostom, NPNF, Part 1, Vol 12, Homily 34).
And? Is there a point here? Your logic seems to be this:
(1) People who prophesy are often wrong.
(2) Therefore prophecy is illegitimate.
That sword cuts both ways, visualize:
(1) Exegetes are often wrong.
(2) Therefore exegesis is illegitimate.
As a matter of fact, Scripture sanctions Direct Revelation, often designated as prophecy (1Cor 14:1) - rather than exegesis - as the
only legitimate epistemology.
"Two or three prophets should speak, and the others should weigh carefully what is said.
30And if a
revelation comes to someone who is sitting down, the first speaker should stop.
31For you can all prophesy in turn so that everyone may be instructed and encouraged" (1 Cor 14).
That same word "revelation" is used in similar passages, notably Mat 11:25 where
The PROPHET Jesus, in typical fashion, looks to "revelation" for His superior knowledge of the Scriptures contra the myriad errors of the exegetes/ scholars - the Sola Scriptura parties of His day consisting of the Pharisees, Sadducees, and Teachers of the law.
"At that time Jesus said, "I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned [
i.e. the Bible scholars], and
revealed them to little children."
Paul himself walked in the erroneous Sola Scriptura mentality until he experienced a Direct Revelation on the Road to Damascus. That was a paradigm shift - for the rest of his life, Direct Revelation became his principal authority. You and Paul got saved (and remain saved) the same way - by an ongoing Direct Revelation known among evangelical scholars as the Inward Witness of the Holy Spirit (Calvin's term).
You MET Christ via a revelation - even if the Light, vision, and voice were more dull for you than for Paul (dullness of revelation is actually due to a lack of revival). Therefore MORE revelation is the only way to know Him better. Hence Paul prayed:
"
17that the God of our Lord Jesus Christ, the glorious Father, may give you a spirit of wisdom and
revelation in your knowledge of Him.
18I ask that the eyes of your heart
b may be
enlightened, so that you may know the hope of His calling, the riches of His glorious inheritance in the saints."
If that word "enlightened" didn't clue you in on the need for illumination, perhaps this passage will:
"For God, who said, “Let light shine out of darkness,”
b made His light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Jesus Christ." (2Cor 4):
Hence Paul prayed:
"For this reason we also, since the day we heard it, do not cease to pray for you, and to ask that you may be filled with the knowledge of His will in all wisdom and spiritual understanding" (Col 1).
Our thoughts have a sonic quality. You can prove this to yourself by mentally singing any words to your favorite tune. As a result, any influence of God upon our minds counts as His voice. Our thoughts are also visual (we comprehend words by visualizing their meanings), hence His influence ALSO counts as visions, for example:
"And we all, who with unveiled faces contemplate
a the Lord’s glory...." (2cor 3:18).
Going back to what you said:
All you've done is underscore the fact that the church has mostly prophesied in presumption throughout history. Indeed the church still hasn't cogently defined how to authenticate a voice. That's where I step in, on numerous threads such as this one:
