It’s nothing new.

The Most Holy One Says:

“It never entered My Mind to Burn people with fire (such as the fire on earth)”

Proof verses? (Let God Himself tell you that – He’s NO Liar):

“They have built the high places of Baal to burn their children in the fire as offerings to Baal–something I did not command or mention, nor did it enter My Mind” (Jeremiah 19:5)

“They built high places for Baal in the Valley of Ben Hinnom to sacrifice their sons and daughters to Molek, though I never commanded–nor did it enter My Mind–that they should do such a detestable thing and so make Judah sin.” (Jeremiah 32:35)

“They have built the high places of Topheth in the Valley of Ben Hinnom to burn their sons and daughters in the fire–something I did not command, nor did it enter My Mind.” (Jeremiah 7:31)

God’s Fire in Chastisement is a Purifying Refiner’s fire “to clean the wicked of their sin and evil” as the verses below declare in Perfect Truth:

“But who can endure the Day of His coming? Who can stand when He appears? For He will be like a Refiner’s Fire or a Launderer’s Soap.” (Malachi 3:2)

“These have come so that the proven genuineness of your faith–of greater worth than gold, which perishes even though Refined by Fire–may result in praise, glory and honor when Jesus Christ is revealed.” (1 Peter 1:7)

“Everyone will be salted with Fire.” – Lord Jesus Christ says “everyone” (Mark 9:49)

You will eventually call Him in the Fire and He Will answer you (for He is Good and Never changes – till your purification is achieved):

“This third I will put into the Fire; I will Refine them like silver and test them like gold. They will call on my name and I will answer them; I will say, ‘They are my people,’ and they will say, ‘The LORD is our God.‘” (Zechariah 13:9)

Need I say more?
Wrong concepts of “God’s Fire” versus our “earthly fire” has caused great sadistic burning and killing of people in the name of religion.

“You will know them by their fruits” – Lord Jesus Christ in (Matthew 7:16)
