5 Bible Verses about The Holy Spirit Described As Fire

There appeared to them tongues resembling fire, which were being distributed [among them], and they rested on each one of them [as each person received the Holy Spirit]. And they were all filled [that is, diffused throughout their being] with the Holy Spirit and began to speak in other tongues (different languages), as the Spirit was giving them the ability to speak out [clearly and appropriately].

When the Lord has washed away the [moral] filth of the daughters of Zion and has cleansed the bloodstains of Jerusalem from her midst, by the spirit of judgment and by the spirit of burning,

“As for me, I baptize you with water because of [your] repentance [that is, because you are willing to change your inner self—your old way of thinking, regret your sin and live a changed life], but He (the Messiah) who is coming after me is mightier [more powerful, more noble] than I, whose sandals I am not worthy to remove [even as His slave]; He will baptize you [who truly repent] with the Holy Spirit and [you who remain unrepentant] with fire (judgment). His winnowing fork is in His hand, and He will thoroughly clear out His threshing floor; and He will gather His wheat (believers) into His barn (kingdom), but He will burn up the chaff (the unrepentant) with unquenchable fire.”

John answered them all by saying, “As for me, I baptize you [only] with water; but One who is mightier [more powerful, more noble] than I is coming, and I am not fit to untie the strap of His sandals [even as His slave]. He will baptize you [who truly repent] with the Holy Spirit and [you who remain unrepentant] with fire. His winnowing fork is in His hand to thoroughly clear His threshing floor, and to gather the wheat (believers) into His barn (kingdom); but He will burn up the chaff (the unrepentant) with unquenchable fire.”

Do not quench [subdue, or be unresponsive to the working and guidance of] the [Holy] Spirit.
