“If you love Me, keep My commandments.  And I will pray the Father, and He will give you another Helper, that He may abide with you forever – the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.  I will not leave you orphans; I will come to you.” John 14:15-18 (NKJV)

“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 14:26

“But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me.” John 15:26
