Ali: Let us discuss a prophecy from John chapter 16: verses 7-8:
“Nevertheless I tell you the truth; it is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment.”1
In some versions of the Bible the Comforter is translated as the Advocate, Pareclete, helper, etc. However, many versions still retain the word Comforter and Pareclete.
John: This verse speaks about the Holy Spirit and not Prophet Muhammed.
Ali: But my dear brother Jesus (a.s.) says: “for if I do not go away, the Comforter will not come to you; but if I go, I will send him to you….”
And according to the Bible, The Holy Spirit was already present on earth even before Jesus’s birth and during his lifetime… let us see a reference from Mathew chapter 3 verse 16 “And Jesus when he was baptized, went up straightway out of the water. And, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting up on him.”2
There is another instance where the Bible speaks about the Holy Spirit being present before the birth of Jesus Christ and that is from Luke chapter 1 verses 39-41:
And Mary rose in those days, and went into the hill country with haste, into a city of Juda; And entered into the house of Zacharias and saluted Elisabeth. And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost.3
From the above verses it becomes clear to us that the ‘comforter’ is not the Holy Spirit because the Holy Spirit was already on earth before Jesus’ (a.s.) birth and during his lifetime and Jesus (a.s.) very clearly says that “If I do not go away the Pareclate will not come to you.”
John: If it is not the Holy Spirit then who is it?
Ali: For answer to this question let us study another reference of the Pareclete in the Gospel of John, John Chapter 14 verse 26 says: “But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.”4
Now; my dear reader, who is the one who came after Jesus Christ and taught all things and brought to remembrance whatever Christ had said?
Come let us see a reference from the Holy Quran, Surah Aale Imran, that is chapter 3 verses 45-48:
When the angels said: O Marium, surely Allah gives you good news with a Word from Him (of one) whose name is the ‘ Messiah, Isa son of Marium, worthy of regard in this world and the hereafter and of those who are made near (to Allah). And he shall speak to the people when in the cradle and when of old age, and (he shall be) one of the good ones. She said: My Lord! When shall there be a son (born) to me, and man has not touched me? He said: Even so, Allah creates what He pleases; when He has decreed a matter, He only says to it, Be, and it is. And He will teach him the Book and the wisdom and the Tavrat and the Injeel.5
