John 14:26 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 that I have said to you.

John 21:25 Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written.

This first verse indicates that the Holy Spirit will bring to memory of all that Jesus said. That comment was said to His disciples, not us.

In the second verse we hear that not everything that Jesus said and did is written down. We do not have a written record to fill in the missing details. The Holy Spirit knows. Will He share with us things not written in His Word?

Ephesians 5:17 Therefore do not be foolish, but understand what the will of the Lord is.

Everything we need is written in the Word.

Hebrews 4:12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.

The Holy Spirit wields the sword to separate fleshly thoughts from the intentions of our hearts that belong to Jesus. In doing so He sheds light on lies and causes us to choose right things, right paths and in doing so changes our lives in ways we cannot do for ourselves.

Since God is One and in perfect harmony, the Holy spirit will not do anything for us or in us that is not the will of the Father. He gives us the desires of our hearts by first changing our heart’s desire.

Given that this is true, do we really need so many volumes of books that we do not have the time to read in the time we have left here on earth?

Ecclesiastes 1:13 And I applied my heart to seek and to search out by wisdom all that is done under heaven. It is an unhappy business that God has given to the children of man to be busy with.

God wants us to be happy. Seeking that which is not revealed by the Holy Spirit is an unhappy business.
