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. John 14:16–17

Then Jesus said to those Jews who believed Him, “If you abide in My word, you are My disciples indeed. And you shall know the truth, and the truth shall make you free.” John 8:31–32
