That verse doesn't say God speaks to us by thoughts or feelings. There is no mention of such a thing. It says your "ears will hear", not your "mind will perceive". You are making 5 huge unwarranted assumptions in order to make the verse say what you want it to say...
- You are presuming "your ears will hear" is a metaphor, rather than literal hearing eg hearing the word preached.
- You are presuming the metaphor (if it is one) is God instructing people via their inner thoughts and feelings. If it is a metaphor it could be a multitude of other things: reading God's word, God's word in your memory, your conscience, etc.
- You are presuming the prophecy applies to every believer. Yet it is addressed to "People of Zion, who live in Jerusalem, ..." (Isa 30:19).
- You are presuming the prophecy is fulfilled in this age. Yet v20 is says "Your eyes will behold your teacher". So that could be when Christ appears in either his 1st or 2nd coming.
- You are presuming that the teacher speaking is the Lord. Yet many bible versions translate the word as 'teachers' (plural), which can only be human teachers, not God. eg NIV "Although the Lord gives you the bread of adversity and the water of affliction, your teachers will be hidden no more; with your own eyes you will see them. Whether you turn to the right or to the left, your ears will hear a voice behind you, saying, “This is the way; walk in it.”
As well as the NIV, many other versions translate it as "teachers" - NIV, NKJV, KJV, ISV, NET, KJ21, ASV, BRG, DARBY, ISV, LEB, NASB, TLV, WEB, YLT
With all those exegetical problems Isa 30:20 is far from being a proof text that God speaks via thoughts and feelings. Let's look at your next verse...
Again you are making the huge unwarranted assumption that "My sheep hear my voice" is believers hearing God speak through their thoughts and feelings. There is nothing to indicate that is what Jesus meant. Jesus is certainly speaking metaphorically here (he is not referring to literal sheep hearing a literal voice), he is referring to believers hearing his words - that I agree. But nowhere in scripture is the Lord's "voice" a metaphor for thoughts and feeling. It is however a frequently used as a metaphor for scripture...
Psalm 103:20 "Mighty in strength, who perform His word, obeying the voice of His word!"
Judges 2:20 "So the anger of the Lord burned against Israel, and He said, “Because this nation has transgressed My covenant which I commanded their fathers and has not listened to my voice"
2 Kings 18:12 "because they did not obey the voice of the Lord their God, but transgressed His covenant, even all that Moses the servant of the Lord commanded;
Psalm 106:24-25 "They did not believe in His word, but grumbled in their tents; they did not listen to the voice of the Lord."
Jer 9:13 "The Lord said, “Because they have forsaken My law which I set before them, and have not obeyed My voice nor walked according to it".
Deut 13:18 "if you will listen to the voice of the Lord your God, keeping all His commandments"
Deut 15:5 "if only you listen obediently to the voice of the Lord your God, to observe carefully all this commandment"
Deut 26:14 "I have listened to the voice of the Lord my God; I have done according to all that You have commanded me."
Ex 19:5 "Now then, if you will indeed obey My voice and keep My covenant"
Ex 23:21 "But if you truly obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries. " (this is Moses speaking)
Dan 9:10 "nor have we obeyed the voice of the Lord our God, to walk in His teachings which He set before us through His servants the prophets."
Daniel 9:11 "Indeed all Israel has transgressed Your law and turned aside, not obeying Your voice;"
1 Sam 12:14 "If you will fear the Lord and serve Him, and listen to His voice and not rebel against the command of the Lord"
1 Sam 12:14 "If you will not listen to the voice of the Lord, but rebel against the command of the Lord,"
Jer 11:3-4 "Thus says the Lord, the God of Israel, “Cursed is the man who does not heed the words of this covenant which I commanded your forefathers ..., saying, ‘Listen to My voice, and do according to all which I command you; so you shall be My people"
Jer 26:12-13 "The Lord sent me to prophesy against this house and against this city all the words that you have heard. Now therefore amend your ways and your deeds and obey the voice of the Lord your God".
Jer 40:2-3 "The Lord your God promised this calamity against this place; and the Lord has brought it on and done just as He promised. Because you people sinned against the Lord and did not listen to His voice, therefore this thing has happened to you".
Psalm 81:11 “But My people did not listen to My voice, And Israel did not obey Me.
So the obvious interpretation of John 10:27 that we will hear Jesus's words through scripture (not via thoughts and feelings).
Don't take that verse out of context. The
"anointing" that
"abides in you" is not referring to thoughts and feelings - there is absolutely no indication of that. Rather it is referring to the same thing that
"abides in you" two verses earlier:
"If what you heard from the beginning abides in you, " v24. ie God's word.
This is confirmed by the end of the passage you quoted (but which you omitted):
v26 but as His anointing teaches you about all things, and is true and is not a lie, and just as it has taught you, you abide in Him.
It cannot refer to God personally speaking as John says that
"it has taught you". Whatever taught them was not a person. John would not use the neuter pronoun is he was referring personally to God or his Spirit.
Again you are taking that verse out of context. The "you" that Jesus refers to in this passage is not every believer, but solely the apostles whom he is addressing. It is part of the same discourse where Jesus instructs the disciples about the coming of the Spirit at Pentecost....
v7 "for if I do not go away, the Helper will not come to you; but if I go, I will send Him to you....".
The "you" here is clearly the 11 disciples. Now look at the verse immediately before the one you quoted (still part of the same discourse),
v12 “I have many more things to say to you, but you cannot bear them now."
It is still clearly addressed to the disciples personally. Then we have your verse, but there is no change of context between v12 and v13. It is the same "you":
v13 "He will guide you [the apostles] into all the truth".
And that is what happened. As spokemen for Christ, the truth was revealed to them by the inspiration of the Spirit.
Being deaf to scripture is a serious condition.
