"And I will ask the Father, and He will give you another Helper, that He may be with you forever; the Spirit of truth, whom the world cannot receive, because it does not behold Him or know Him, but you know Him because He abides with you, and will be in 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 abode with him." (John 14:16-17, 23)
if the spirit has the ability to come to you and dwell in you teaching you things, assisting you in your walk with god, and revealing truth about god to you, then it is evident that when jesus says "we will come to him and make our abode with him", he is saying that the father, the son, and the holy spirit are one, because God is one, and by accepting christ, then you accept the father who sent him, and when you accept the holy spirit that christ sent, you have in actuality accepted the father, the son, and the holy spirit into your life as the holy spirit dwells with you.
