14:16-- "to be with you forever" (A human being doesn't live forever.)
14:17-- "the spirit of truth" (A human being is distinct from spirit.)
14:17-- "The world ... neither sees him" (A human being is visible.)
14:17-- "nor knows him" (A human being would be known by others.)
14:17-- "he ... will be in you" (A human being cannot be within others.)
Regarding "to be with you forever" the point is a reference to the fact that his message will last for ever. Consider the following:
"Verily, verily, I say unto you, If a man keep my saying, he shall never see death. Then said the Jews unto him, Now we know that thou hast a devil. Abraham is dead, and the prophets; and thou sayest, If a man keep my saying, he shall never taste of death. Art thou greater than our father Abraham, which is dead? and the prophets are dead: whom makest thou thyself? Jesus answered, If I honor myself, my honor is nothing: it is my Father that honoureth me; of whom ye say, that he is your God: Yet ye have not known him; but I know him: and if I should say, I know him not, I shall be a liar like unto you: but I know him, and keep his saying."
John 8:51-55
and also
"And I (Jesus) give unto them (the believers) eternal life; and they shall never perish, neither shall any man pluck them out of my hand."
John 10:28
and "and my servant David [shall be] their prince forever."
Ezekiel 37:25.
and "The king shall joy in thy strength, O LORD ... He asked life of thee, [and] thou gavest [it] him, [even] length of days for ever and ever."
Psalm 21:1-4
... etc.
Jesus (pbuh) is quoted many times in the Bible as telling his followers that they will never taste death. However, there is not a single one of them alive to this day. Was he lying? Of course not! As seen above, Jesus' (pbuh) was not telling mankind that his followers would never grow old nor die, rather he was speaking about their second life in the hereafter. He was telling them that the life that we hold so dear and spend so much time fretting over and striving to improve is all but insignificant if compared to the true life, the afterlife. So much so that life and death on this earth is unworthy of consideration. Everything in his estimation revolved around an eternal striving for the reward of the afterlife and this was the yardstick by which all matters were to be measured.
In a similar manner, when king David is described as being a prince forever, this did not mean that he would never die but remain immortal for ever and ever as a prince to Israel. Rather, his teachings, name, and guidance shall remain as a shining beacon to mankind even after his death. In this manner, Jesus (pbuh) lives among us through his faith and teachings, prophet Abraham (pbuh) lives on among them and us through his faith and teachings, and so too, the coming Paraclete will live eternally with us through his faith and teachings.
The Paracletos will be the last prophet, because he will "abide with you forever" and "he will guide you into all truth" (Greek "into the whole truth") and "he shall teach you all things," so there will be no need for any further prophets. In the Qur'an we read:
"Muhammad is not the father of any man among you, but he is the messenger of Allah and the Seal of the Prophets; and Allah is Aware of all things."
The noble Qur'an, , al-Ahzab(33):40
And "This day have I (God) perfected your religion for you (mankind) and completed My favor unto you, and have chosen for you as religion Islam(the submission)."
The noble Qur'an, al-Maidah(5):3
So the religion of Islam is the last message to mankind and it, as well as the Qur'an, will abide with them forever. To this day, Muhammad (pbuh) abides with us through his teachings. Muhammad (pbuh) indeed remains alive and well among us in the vast collection of over 9,500 quotations recorded from him during his lifetime in a broad range of topics. This collection of quotations is named the "Hadeeth." To this day, whenever a Muslims wishes to perform any action no matter how trivial, he does not advance a single step before first consulting Allah/God (in the Qur'an), and then prophet Muhammad (pbuh) (in the Hadeeth). Be it a question on how and what to eat or drink, how to perform marriages, how to pray, what sort of trade or commerce is permissible or prohibited, or what sort of clothes to wear, no Muslim presumes to undertake any action before first obtaining the approval of God then His prophet. Muhammad (pbuh) truly is alive and well among us.
So Jesus is saying that the comforter will abide forever in his teachings. 1.5 Billion Muslims are living proof that his message has abided and will further be with us until Doomsday.
Next, The Term "Spirit Of Truth". As i have stated before the word Spirit does not always concern the Holy Ghost, or something that is not Human. For example John uses the terms Spirit and Prophet Interchangabley with each other.
"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world,"
1 John 4:1-3:
Here we see that A False Spirit is a False Prophet, and a true Prophet is a true spirit. See also 1 John 4:6
"...which the world cannot recieve because it niether beholds it nor knows it..." This still can fit Muhammed. Jesus says the 'world can not recieve' him. Why? Because the world is not fit to recieve him. Compare it too 'i have yet many things to say unto you, but ye cannot BEAR THEM NOW...'
"It neither beholds it, nor knows it" All Jesus is trying to say here is that the spirit of truth has not yet been sent, so nobody knows it yet, but when he comes he will guide man 'into all truth'.(Juhn 16:13) I ask again,What new truths has the Holy Ghost brought into the world in the last 2000 years other than what Jesus himself brought. So back to "neither beholds it or knows it", it merely means that the Spirit of Truth (Muhammed) is not in the world yet, and is yet to come.
The terms 'he is in you' is again metephorical, and this is the language that Jesus commonly used.
14:26--"whom the Father will send in my [Jesus'] name"
14:26--"will remind you of everything I [Jesus] have said to you"
16:08--"He will convict the world of guilt in regard to sin"
16:14--"He will bring glory to me [Jesus]"
These were all answered in my previous post but, just to reemphasize on the fact reminding 'of everything' Jesus Said, cannot possibly refer to the Holy Ghost. How can the Holy Ghost Remind people. The Christian would say he can inspire, but how can we ever prove what someone has been inspired by? No, what he is talking about is someone, a human, who will remind people about the fact that Jesus came on the earth, that he was the Messiah, and was a prophet Of God. He will also remind specifically, the Mission of Jesus to the People. Now why would the Paraclete need to do that. Because Jesus knows that the Paraclete will come at a time when his message will have been distorted, and people will have strayed, believing that he is God and the begotten son of God. Otherwise, why does the Paraclete need to Remind. There is a definite purpose behind this, and one which Muhammed did indeed fullfil.
14:17--"the Spirit of Truth"
14:26--"the Counsellor [parakletos], the Holy Spirit"
I have no hesitation, and nor does any Muslim, in accepting that Muhammed is a spirit of Truth, because as i stated earlier the term spirit does not always have the same meaning. Spirit is used interchangabley with Prophet :
"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world," 1 John 4:1-3
Also Spirit of truth corresponds with the title that was given to the Prophet Muhammed, Al-Amin, meaning the trustworthy, a title that he was given way before prophethood, when he was a child.
