4 Bible Verses about The Holy Spirit Described As Fire

And there was an appearance to them of divided tongues, as of fire, and it rested on every one of them. And they were all filled with the Holy Ghost, and they began to speak with other tongues, as the Spirit gave them power to express themselves.

I indeed baptize you with water unto repentance: but he that is coming after me is mightier than I, whose sandals I am not worthy to carry: he shall baptize you with the Holy Spirit, and with fire: whose winnowing fan is in his hand, and he will thoroughly cleanse his threshing floor, and will collect the wheat into his granary; but the chaff will he burn up with fire unquenchable.

John addressed himself to them all, saying, I indeed baptise you with water; but one mightier than I is coming, the thong of whose sandals I am not worthy to untie: he shall baptise you with the Holy Ghost and with fire; whose winnowing fan is in his hand, and he will thoroughly cleanse his threshing-floor, and collect the wheat into his granary; but the chaff he will burn with fire unquenchable.

Quench not the Spirit.
