So the Advocate was going to teach and remind one of all Jesus said.
You seem to believe it is you the Advocate is teaching. Yet you don't recognise the Advocate as a person.
Who does Jesus repeatedly contribute the words he was speaking to
You are still hung up on words.
6 Jesus answered,“I amthe wayand the truthand the life.No one comes to the Father except through me.7 If you really know me, you will know[b]my Father as well.From now on, you do know him and have seen him.”
Knowing and seeing. Just as knowing and seeing the Holy Spirit.
16 And I will ask the Father, and he will give you another advocateto help you and be with you forever—17 the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him.
Quote wotsup: "John 3:34For he whom God hath sent speaketh the words of God:for (because)God giveth not the Spirit by measureunto him. Luke 4:18 -The Spirit of the LORD is on Me,because He has anointed Me to preach good news to the poor. He has sent Me to proclaim liberty to the captives and recovery of sight to the blind, to release the oppressed," unquote:
The verses you give are before Jesus is crucified and before being accused of blaspheme. Jesus' time was to come later to reveal himself. You are still unable to comprehend why Jesus was crucified. How you are unable to grasp it is astounding.
