4 Bible Verses about The Holy Spirit Described As Fire

There appeared to them tongues, like flame, distributing themselves, one resting upon the head of each one, and they were all filled with the Holy Spirit, and began to speak with other tongues as the Spirit was giving them utterance.

I indeed am baptizing you in water, unto repentance; but One is coming after me, mightier than I, whose sandals I am not worthy to carry. He will baptize you in the Holy Spirit and in fire. His winnowing-fan is in his hand, and he will thoroughly cleanse the threshing-floor. He will store his wheat in the granary, but will burn up the chaff in unquenchable fire."

whether perhaps he were the Christ, John answered, saying to all of them. "I indeed am baptizing you in water, but One is coming after me, mightier than I, whose shoe-latchet I am not worthy to unloose. He shall baptize you in the Holy Ghost and in fire. He has his fan in his hand to cleanse his threshing-floor thoroughly, and to gather the wheat into his storehouse, but the chaff will he burn with unquenchable fire."

Quench not the Spirit.
