The fire yes (because it's God's presence). But the stay is temporary.
"I kept looking Until thrones were set up, And the Ancient of Days took His seat; His vesture was like white snow And the hair of His head like pure wool. His throne was ablaze with flames, A river of fire was flowing And coming out from before Him; Thousands upon thousands were attending Him, And myriads upon myriads were standing before Him; The court sat, And the books were opened. (Dan 7:9-10)
Divine fire purifies.
Then I said, "Woe is me, for I am ruined! Because I am a man of unclean lips, And I live among a people of unclean lips; For my eyes have seen the King, the LORD of hosts."
Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the altar with tongs.He touched my mouth with it and said, "Behold, this has touched your lips; and your iniquity is taken away and your sin is forgiven." (Is 6:5-7)
If one hot coal from the brazier can cleanse sin, how much more full immersion in the fire?
