"And I (Jesus) will pray (to) the Father, and He will give you another Helper, that He may abide with you forever -- the Spirit of truth … you know Him, for He dwells with you and will be in you. I will not leave you orphans; I will come to you. … If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. … 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 things that I said to you." (John 14:16-26). The Greek word here for "another" is "allos" meaning "another of the same kind" (ref: Vine). So, the Holy Spirit is another Person of the Triune Godhead (like God the Son). It seems to say that ... all 3 Persons of the Triune God will come to be with the faithful believer, but only the Holy Spirit will remain in him/her forever (i.e. until death), and only the Holy Spirit will be the One doing the teaching. Interesting, what?
