Unquenchable Fire

Many Christians believe the biblical term “unquenchable fire” refers to an unending fire, one that burns someone/something forever and ever and ever. Here are a couple passages in which the term is used:

“His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather His wheat into the barn; but He will burn up the chaff with unquenchable fire” (Matthew 3:12).

“And they shall go forth and look upon the corpses of the men who have transgressed against Me. For their worm does not die, and their fire is not quenched. They shall be an abhorrence to all flesh.” (Isa. 66:24).

As stated above, many Christians say “unquenchable fire” refers to unending fire. However, the scriptural evidence shows it refers to an unstoppable fire. That is, when God decides that something will be burned up (judged), nobody can extinguish the fire (stop the judgment) until it completes its objective. That’s why it’s called unquenchable.

This definition is confirmed in the following passage:

“And Bethel shall come to nothing. Seek the Lord and live, lest He break out like fire in the house of Joseph, and devour it, with no one to quench it in Bethel” (Amos 5:6).

As this passage shows, when God determines that fire will break out—that a judgment will happen—nobody can stop it or put it out until it completes its purpose. That’s why it is called unquenchable.

But this does not mean the fire itself—or the thing being burned—will burn forever. In fact, God had warned about many unquenchable fires in Old Testament times (see Jer. 7:20, 17:27; Ezek. 20:47)—which were followed by judgments—yet these fires are not still burning today.

Sodom and Gomorrah suffered “eternal fire” (Jude 7); yet if we visited that area today, we would not see it burning.

The context of the passage cited above, Matthew 3:12, shows this too:

“And even now the ax is laid to the root of the trees. Therefore every tree which does not bear good fruit is cut down and thrown into the [unquenchable] fire…His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather His wheat into the barn; but He will burn up the chaff with unquenchable fire” (Matt. 3:10-12).

This unquenchable fire—which refers to the judgment of Israel—was about to happen when this passage was written. And it did happen by the year AD 70, when the city of Jerusalem and the temple were destroyed. The Romans even used fire to burn down the city and temple! The first century historian Josephus says 1.2 million Jews were killed, and another 97,000 were taken into slavery.

This was the fulfillment of Matthew 3:10-12…yet this fire is not still burning.

The term “unquenchable fire” is typical Hebraic judgment language. It’s apocalyptic language. And it was meant no more literally than when someone today threatens to “burn down your world”; or when someone today says he’s going to “set the world on fire.”
