If I bear witness of myself, my witness is not true.  There is another that beareth witness of me; and I know that the witness which he witnesseth of me is true.
At the mouth of two witnesses, or three witnesses, shall he that is worthy of death be put to death; but at the mouth of one witness he shall not be put to death (Deut. 17:6).
One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established (Deut. 19:15).
 Ye sent unto John, and he bare witness unto the truth.  But I receive not testimony from man: but these things I say, that ye might be saved.  He was a burning and a shining light: and ye were willing for a season to rejoice in his light.
 But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.
 And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.  And ye have not his word abiding in you: for whom he hath sent, him ye believe not.
 "Father, glorify thy name."Then came there a voice from heaven, saying, "I have both glorified it, and will glorify it again." The people therefore, that stood by, and heard it, said that it thundered: others said, An angel spake to him. Jesus answered and said, "This voice came not because of me, but for your sakes."
 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book. And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt. And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever. But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
 I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire. A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened.
 And ye will not come to me, that ye might have life.  I receive not honour from men.  But I know you, that ye have not the love of God in you.  I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.  How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?
 Do not think that I will accuse you to the Father: there is one that accuseth you, even Moses, in whom ye trust.  For had ye believed Moses, ye would have believed me: for he wrote of me.  But if ye believe not his writings, how shall ye believe my words?
 Abraham saith unto him, "They have Moses and the prophets; let them hear them." And he said, "Nay, father Abraham: but if one went unto them from the dead, they will repent." And he said unto him, "If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead."
 And he came thither unto a cave, and lodged there; and, behold, the word of the Lord came to him, and he said unto him, "What doest thou here, Elijah?" And he said, "I have been very jealous for the Lord God of hosts: for the children of Israel have forsaken thy covenant, thrown down thine altars, and slain thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away." And he said, "Go forth, and stand upon the mount before the Lord."
And, behold, the Lord passed by, and a great and strong wind rent the mountains, and brake in pieces the rocks before the Lord; but the Lord was not in the wind:
and after the wind an earthquake; but the Lord was not in the earthquake:
 And after the earthquake a fire; but the Lord was not in the fire:
and after the fire a still small voice.
It is worth keeping in mind that this statement, "the Lord was not in the fire," comes shortly after the famous episode in which, having first challenged the 450 prophets of Baal to do the same, Elijah calls down fire from heaven to consume his sacrifice, and the wood, and the stones of the altar. "And when all the people saw it, they fell on their faces: and they said, The Lord, he is the God; the Lord, he is the God" (1 Kgs. 18:29). Well, we see how long that lasted! In the very next chapter, Elijah is once more all alone in his faith and is praying for the Lord to take away his life. The Lord, despite the people's immediate reaction to the miracle, was not in the fire.
"The Lord was not in the wind" -- but he was, wasn't he? "The Lord passed by, and a great and strong wind rent the mountains, and brake in pieces the rocks before the Lord." The text is not saying that the wind had nothing to do with the Lord -- it was apparently caused by him, directly and miraculously, just like the fire from heaven that consumed the altar. But it was not him; he was not in it -- and those who saw it did not really see him and were not really converted. I discussed this in my notes on John 1, commenting on the seemingly false statement that "no man hath seen God at any time."
God as such cannot be seen even in principle, because divinity has nothing whatever to do with being a physical object that produces or reflects light. Even those who saw Jesus Christ face to face saw just that: his face, and other parts of his physical body. That is, they may have seen directly that he was a man, but they could not have seen, in the same direct sense, that he was God. That in him which made him God could not be seen. Even those who saw him work miracles saw only that: a man with paranormal powers, which is not at all the same thing as God. . . . No conceivable sort of empirical observation could ever, even in principle, amount to an observation of God qua God.
"He be not far from every one of us . . . for we are also his offspring" (Acts 17:27-28). "The kingdom of God cometh not with observation . . . for, behold, the kingdom of God is within you" (Luke 17:20-21). We can know God as God only because -- and only to the extent that -- his nature resonates with something in our own, with the spark of divinity within. "He called them gods, unto whom the word of God came" (John 10:35), because ultimately the divine Logos can come to none other. "Deep calleth unto deep . . . and in the night his song shall be with me, and my prayer unto the God of my life" (Ps. 42:7-8).
William Blake alludes to 1 Kings 19 in the dedication of The Ghost of Abel -- a dedication that cut me to the quick when I first read it years ago, back when I was a bloviating atheist, because the phrase "Lord Byron in the Wilderness" punctured with voodoo-doll precision the rather ridiculous self-image I was then entertaining.
To Lord Byron in the Wilderness:
WHAT doest thou here, Elijah?
Can a Poet doubt the Visions of Jehovah? Nature has no Outline,
But Imagination has. Nature has no Tune, but Imagination has.
Nature has no Supernatural, and dissolves: Imagination is Eternity.
William Blake was always right. Change my mind.
