'Fire' in the Bible

But by His word the present heavens and earth are being reserved for fire, being kept for the day of judgment and destruction of the ungodly people.

But the day of the Lord will come like a thief, and then the heavens will vanish with a [mighty and thunderous] roar, and the [material] elements will be destroyed with intense heat, and the earth and the works that are on it will be burned up.

[while you earnestly] look for and await the coming of the day of God. For on this day the heavens will be destroyed by burning, and the [material] elements will melt with intense heat!
