16 And I will ask the Father, and he shall give you another Paraclete, that he may abide with you for ever. 17 The spirit of truth, whom the world cannot receive, because it seeth him not, nor knoweth him: but you shall know him; because he shall abide with you, and shall be in you. 18 I will not leave you orphans, I will come to you. 19 Yet a little while: and the world seeth me no more. But you see me: because I live, and you shall live. 20 In that day you shall know, that I am in my Father, and you in me, and I in you.
*16 “Paraclete”… That is, a comforter: or also an advocate; inasmuch as by inspiring prayer, he prays, as it were, in us, and pleads for us.
16 “For ever”… Hence it is evident that this Spirit of Truth was not only promised to the persons of the apostles, but also to their successors through all generations. *
This is directly from Jesus…He will send us the truth but we must accept it (KNOW, LEARN)
And…
26 But the Paraclete, the Holy Ghost, whom the Father will send in my name, he will teach you all things, and bring all things to your mind, whatsoever I shall have said to you. 27 Peace I leave with you, my peace I give unto you: not as the world giveth, do I give unto you. Let not your heart be troubled, nor let it be afraid. 28 You have heard that I said to you: I go away, and I come unto you. If you loved me, you would indeed be glad, because I go to the Father: for the Father is greater than I. 29 And now I have told you before it comes to pass: that when it shall come to pass, you may believe. 30 I will not now speak many things with you. For the prince of this world cometh, and in me he hath not any thing.
*26 “Teach you all things”… Here the Holy Ghost is promised to the apostles and their successors, particularly, in order to teach them all truth, and to preserve them from error.
28 “For the Father is greater than I”… It is evident, that Christ our Lord speaks here of himself as he is made man: for as God he is equal to the Father. (See Phil. 2.) Any difficulty of understanding the meaning of these words will vanish, when the relative circumstances of the text here are considered: for Christ being at this time shortly to suffer death, signified to his apostles his human nature by these very words: for as God he could not die. And therefore as he was both God and man, it must follow that according to his humanity he was to die, which the apostles were soon to see and believe, as he expresses, ver. 29. And now I have told you before it come to pass: that when it shall come to pass, you may believe.*
31 But that the world may know, that I love the Father: and as the Father hath given me commandment, so do I: Arise, let us go hence.
