Role of the Spirit

John 14:16-17 AMP
16 And I will ask the Father, and He will give you another [c]Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby), to be with you forever— 17 the Spirit of Truth, whom the world cannot receive [and take to its heart] because it does not see Him or know Him, but you know Him because He (the Holy Spirit) remains with you continually and will be in you.
