We are in agreement on that point. Except for the "she" part. (unbiblical)
The Spirit, not just the word, guides us into all truth. And tells us what is to come. (prophecy)
John 16:12-14
“I have much more to say to you, more than you can now bear. 13 But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. 14 He will glorify me because it is from me that he will receive what he will make known to you.
The disciples needed instruction in order to grasp the instruction which they'd received from Jesus. This would be provided for by the Spirit, whose function would be truth's teaching.
She'll teach them. She'll bring them into the truth, make them familiar with it, let them grasp the truth, have them realize God's grace in Jesus. In doing this, she won't display an independent activity.
The relation between the Godhead's persons is unity. The Spirit can and will lead the believers into truth, because she'll speak what she's heard in the Godhead. She'll speak the Trinity's words as such.
The Spirit wants to be with and in the Word, and through it lead us into truth, keeps us against lies, and helps us conquer in trials. So she reveals God.
She'll tell of things to come. The future salvation also belongs to God. Jesus' coming to judge, the consummation of the redemption in God's Kingdom. In regard to these the Spirit will give the information.
In doing so, her work will be for Jesus, since the truth which she'll reveal she'll receive from Jesus for preaching. By picturing Jesus before believers, the Spirit gives to Jesus the glory which is due him.
In taking her doctrine from Jesus, the Spirit receives her doctrine from God, for since they've the Godhead in common, they've also the divine knowledge in common.
Christ here makes a statement that couldn't be made by a mere man. "All that God has," he says, "is Mine." He has power over it, for he and God have everything in common.
The Spirit has the Godhead to draw from, in the believers' interest. That's the Spirit's work for and in the believers, that she teaches them to know Christ.
