Just as His disciples speak of Jesus Christ as led by the Holy Spirit to do. His disciples are not led by the Holy Spirit to speak of the Holy Spirit in seeking His own glory, but the gospel of Jesus Christ in seeking His glory.Joh 15:26 “And I will send you the Divine Encourager from the very presence of my Father. He will come to you, the Spirit of Truth, emanating from the Father, and he will speak to you about me. (TPT)
John 15:26 But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
27 And ye also shall bear witness, because ye have been with me from the beginning.
John 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
14 He shall glorify me: for he shall receive of mine, and shall shew it unto you.
That is what a true witness does and the Holy Spirit is that perfect Witness.
John 3:28 Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him.
29 He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled.
30 He must increase, but I must decrease.
John 5:31 If I bear witness of myself, my witness is not true.
John 7:18 He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.
When believers puts the spotlight on the Holy Spirit in worship, prayer, or fellowship, in seeking the glory of the Holy Spirit, they are not led by the indwelling Holy Spirit nor by scripture to do that, but are in iniquity. That does not mean they do not have the Holy Spirit, but they are not being led by scripture nor the indwelling Holy Spirit to do that thereby grieving the Holy Spirit in them.
John 10:1Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber....
7 Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep.
John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
