From your John Owen reference, this is what I have been trying to explain to the other guys. Perhaps they will see it in reformed terminology.

THE NATURE OF THIS WORK OF THE SPIRIT

The Holy Spirit does this work by teaching ‘The unction teaches you.’ This does not refer to his direct inspiration, that is, his bringing new sacred truths from God directly to the minds of men. This is how he taught the apostles and prophets (1 Pet. 1:11-12; 2 Pet. 1:21). Nor does God grant new revelations to preserve his people from error. God has made sufficient provision in his Word for that (Isa. 8:20; 2 Pet. 1:19).

The teaching referred to is his enabling us to discern, know and understand the mind and will of God as revealed in the Scriptures.

It is not enough simply to know the truth. We must also be assured in our minds that we do really know it (Eph. 4:14; Col. 2:2). This assurance is given by the Holy Spirit ‘who is truth and is not a lie’. There is no possibility of anyone being deceived in what he is taught by this ‘unction’. The Holy Spirit gives to believers a secret witness to what he teaches, along with his teachings (1 John 5:6). There is a special power accompanying the teaching of God by his Spirit (Job 36:22; John 6:45). So whoever is taught in this way certainly believes the things he is taught, having the evidence of the truth of them in himself (1 John 5:10).

Spiritual sense and judgment are able to discern the divine evidences in the things the Holy Spirit teaches (Heb. 5:14). This is what gives the mind the highest assurance of the truth that it is able to have in this world.

The testimonies we have considered are sufficient to establish this first general assertion: It is the Holy Spirit who teaches us to understand aright the mind and will of God in the Scripture. Without his aid we could never do this usefully and profitably to our souls.

The great promise of the New Testament is that all believers shall be ‘taught by God’ (John 6:45; see also 1 Thess. 4:9). No man is self-taught in sacred things.

Who will the Holy Spirit teach? He will teach those who are meek and humble, those who give themselves to continual prayer, meditation and study in God’s Word day and night, and those who strive to conform their lives to the truths he instructs them in. Because these are hard conditions to flesh and blood, there are few who apply to study in the school of God, while many will apply to other teachers, especially to the church of Rome, where no cost in self-denial need be involved.

I understand the reformed aversion to the word revealed, revelation etc., but scripture does use it, so we cannot shy away from it either.

1 Cor 2:9-11 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. 10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. 11 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.
