Oh He is Holy. The Holy Spirit teaches us with the verses. By quoting them.
26 "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.
The Holy Spirit is not allowed to speak to us any other way.
13 "However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come.
14 "He will glorify Me, for He will take of what is Mine and declare it to you.
This Holy Spirit the one that only quotes verses is the only guarantee of salvation in the whole bible.
2 Cor 5:5
5 Now He who has prepared us for this very thing is God, who also has given us the Spirit as a guarantee.
The Holy Spirit brings us the wisdom from above. And He will never work on us through our feelings.
17 But the wisdom that is from above is first pure, then peaceable, gentle, willing to yield, full of mercy and good fruits, without partiality and without hypocrisy.
