And it John 14:17, John is referring to the Helper. The Helper is the Spirit of Truth. The Helper is not just gifts and knowledge, but God who lives within us.
"I will ask the Father, and He will give you another Helper, so that He may be with you forever; 17 the Helper is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him; but you know Him because He remains with you and will be in you."
What does it mean "another" Helper? Jesus is leaving them, and He has been with them and helping them learn and grow. "Another" refers to someone (not something) else that will come and live with them and in them (and with and in us who are in Christ).
