“It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.” (John 6:63) (KJV 1900)
This is where the Baptism of the Holy Spirit comes from. Not out of thin air like many assume.
Holy Spirit comes from God, and He can only say what He has being told, so if God has nothing to say, neither has He.
1Jn_2:27 But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.
And revelation comes from God, without it the bible is just a book,
Isa 29:10 For the LORD hath poured out upon you the spirit of deep sleep, and hath closed your eyes: the prophets and your rulers, the seers hath he covered.
Isa 29:11 And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed:
Isa 29:12 And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned.
Isa 29:13 Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
1Co_2:10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
