John 14:26

But the Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby), the Holy Spirit, whom the Father will send in My name [in My place, to represent Me and act on My behalf], He will teach you all things. And He will help you remember everything that I have told you. [Matt 5:7, 13, 24, 25; Luke 24:49; John 14:16; Acts 1:4]
