John meets the captain of the Spaceship

And He who sat there looked like a jasper stone and a sardius. And a rainbow was around the throne, looking like an emerald. Rev 4:3 

A Sighting of Jehovah

At this point of the book, John is in the presence of the Father of Jesus Christ.  That it was not Christ sitting on the throne will become evident shortly. The description that John gives is of God the Father, and the portrayal is in reference to position and colour.

  

John says God, the Father, was sitting and He who sat there was like a jasper and a sardius stone in appearance.  The dictionary says that a jasper is a coloured quartz usually red or brown and that the sardine or sardonyx is a brownish-red variety of chalcedony.  Therefore, isn't it possible to believe that the one sitting on the throne in The Apocalypse appeared to John to be wearing reddish-brown clothing because he is bathed in a green light and surrounded by a red fiery flame?  Green and red together appear brown.  I watched until the thrones were set in place, and the Ancient of Days sat ... His throne was like flames of fire, and His wheels like burning fire. Dan. 7:9.  

   In speaking of the physical appearance of Jehovah, Daniel said, the Ancient of Days was seated; His garment was white as snow, And the hair of His head was like pure wool. Dan. 7:9.  We cannot believe, as some Bible scholars tell us, that this refers to Christ because separate reference is made to Christ, in Daniel 7:13.  One like the Son of Man, Coming with the clouds of heaven! Christ is arriving in a spaceship!  He came to the Ancient of Days, And they brought Him near before Him.  Daniel sees Christ being ushered into the presence of His Father, the One whom Daniel had just seen.  There is nothing here to indicate that either of them (the Father and the Son) were not in physical form.  On the contrary, the argument stands firm that since Daniel saw them with his physical eyes they must both be physical.

Much has been written about Ezekiel and his association with spaceships, and a few words from Ezekiel add weight to John's description. And above the firmament over their heads was the likeness of a throne, in appearance like a sapphire stone; on the likeness of the throne was a likeness with the appearance of a man high above it. Also from the appearance of His waist and upward I saw, as it were, the color of amber with the appearance of fire all around within it; and from the appearance of His waist and downward I saw, as it were, the appearance of fire with brightness all around. 1:26-27.  Obviously, Ezekiel is describing the same scene as John did, only in reverse order.  If we read it carefully, we notice that Ezekiel said that in appearance Jehovah is like a man.

   In 4:3 the words, in the KJV, He who sat there, are omitted in "The Majority Texts".  Supposing, them to be the right translation, for now, verses 2-3 read like this, behold, a throne set in heaven, and one sat on the throne which was like a jasper and a sardius stone in appearance.  Some argue that, according to this text, even though the Father was sitting on the throne the text does not say that John saw Him; the description was about the throne.

   However, the statement that John saw the Father, with his physical eyes, must stand without challenge; in 20:11, John writes, I saw a great white throne and (I saw) Him who sat on it.  We remind ourselves again, that Abraham, Jacob, Moses, Ezekiel, Isaiah, Daniel and John all claim that they saw God, the Father, as a physical being.  

   These various Bible narratives force us to conclude that, the one whom Saint Paul called invisible, has been seen, in His physical nature, by certain “men of God”.  This does not at all imply that Paul contradicts the other scribes of the Bible.  Any one of us that have never seen God must admit that, to us, as to Paul, God is invisible.
