What Elijah did was per instruction of the Lord, which was also to be
sign given for those who can recieve it.
Also that
fire come down from heaven was also a
sign given, which is revealed to us in Jeremiah...
Jeremiah 5:14
Wherefore thus saith the LORD God of hosts, Because ye speak this word, behold,
I will make my words in thy mouth fire, and
this people wood, and it shall
devour them.
The
Word of God can
baptize with the
Holy Spirit, and with
Fire.
There is of course both spiritual and literal fire.
Noticed what happened during the destruction of the Temple in AD 70 by the Roman army:
The Destruction of Jerusalem - George Peter Holford, 1805AD

The Romans, wilfully deaf instead of extinguishing the flames, spread them wider and wider.
Meanwhile the Temple continued burning, until at length, vast as was its size, the flames completely enveloped the, whole building ; which, from the extent of the conflagration, impressed the distant spectator with an idea that the whole city was now on fire. The tumult and disorder which ensued upon this event, it is impossible (says Josephus) for language to describe. The Roman legions made the most horrid outcries ; the rebels, finding themselves exposed to the fury of both fire and sword, screamed dreadfully ; while the unhappy people who were pent up between the enemy and the flames, deplored their situation in the most pitiable complaints...............
