You know you would understand scripture much better if you separated the ones pertaining to salvation from those pertaining to discipleship/walking in the Spirit and living as a new creation.
But when he, the Spirit of truth, comes, he will guide you into all 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.
He will bring glory to me by taking from what is mine and making it known to you.
All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you.

You cannot separate the parts of the gospel, because they form an eternal whole, that takes time and following to see.

But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil
Trying to correct someone who know good from evil suggests error.
