HOLY SPIRIT = SPIRIT OF THE LORD = SPIRIT OF Y-H-V-H.

Joh 14:26
But the Comforter, which is the HOLY SPIRIT, whom the Father will send in My Name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
HOLY SPIRIT is sent in YESHUA's Name, shall TEACH and REMIND us all things YESHUA had said.
YESHUA says :
Mat 5:17
Think not that I am come to destroy the TORAH, or the PROPHETS: I am not come to destroy, but to fulfil.
HOLY SPIRIT will remind us about it also.
