In this sermon A Baptism By Fire, Both John the Baptist and the Lord were on to something when they promised the work of fire.  Sometimes we want to focus in on the power of the Holy Spirit but not the power of the fire.  Or even that our understanding of the baptism of fire is totally opposite of what God fully intended. Fire is one of the most powerful symbols in human language.  In it’s uncontrolled state it's an object of dread, but it still is the source of immense blessing to men.  It becomes that agent of progress and change.
