He may even have literal fire as part of Himself...
He does in Ezekiel's vision...
4And I looked, and, behold, a whirlwind came out of the north, a great cloud, and a fire infolding itself,
and a brightness was about it, and out of the midst thereof as the colour of amber, out of the midst of the fire.
26And above the firmament that was over their heads was the likeness of a throne, as the appearance of a sapphire stone: and upon the likeness of the throne was the likeness as the appearance of a man above upon it.
27And I saw as the colour of amber, as the appearance of fire round about within it,
from the appearance of his loins even upward, and from the appearance of his loins even downward, I saw as it were the appearance of fire,
and it had brightness round about.
28As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell upon my face, and I heard a voice of one that spake.
And, in John's...
5And out of the throne proceeded lightnings
and thunderings and voices: and there were seven lamps of fire burning
before the throne, which are the seven Spirits of God.
