kjv@John:14:19@ Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
kjv@John:14:20@ At that day ye shall know that I am in my Father, and ye in me, and I in you.
kjv@John:14:21@ He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
kjv@John:14:22@ Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world?
kjv@John:14:23@ Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
kjv@John:14:24@ He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
kjv@John:14:25@ These things have I spoken unto you, being yet present with you.
kjv@John:14:26@ 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.
kjv@John:14:27@ Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
kjv@John:14:28@ Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I.
kjv@John:14:29@ And now I have told you before it come to pass, that, when it is come to pass, ye might believe.
kjv@John:14:30@ Hereafter I will not talk much with you: for the prince of this world cometh, and hath nothing in me.
kjv@John:14:31@ But that the world may know that I love the Father; and as the Father gave me commandment, even so I do. Arise, let us go hence.
An important aspect of faith is being taught here. It is one thing to believe "in" a Jesus that has your ticket to heaven. It is another to believe to the point of His Lordship in your daily life; to believe to the point of knowing and obedience. It is the test of true love.
This is a partial list of the Comforter's responsibilities. These abilities had until now only been shadowed in OT prophets. The HolyGhost is crucial to the believer in order to know and conduct daily relations, therefore obedience to our Lord.
Anything we ask? Or anything that will glorify the Father in the Son? Surely, if the Lord commanded that we did one thing and we lacked the resource He would honor our obedience, but, what about in our disobedience?
It is a deliberate attempt on the part of the critic to eliminate the presence and duties of the Holy Ghost. Arguments can be made and well supported that left to man's interpretation and translation and tendency to bend truth around one's own will, more persuasively by displacing the function of the Holy Spirit. Otherwise, God did not merely leave it in our own incapable hands, God did not make it all dependent upon our powers of deduction, God did not leave it up to our own personal and corporate misunderstandings. Their argument ends at the ability of the Comforter sent in Jesus' name to teach and put us in remembrance of (amongst other things). Coincidentally, it is the blasphemy against this triune entity that is the "unpardonable sin".
