well since so many here are sharing opinions, I figured I might offer mine.
I read three baptisms.
Mat 3:11 I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire
Water
Spirit
Fire
IN fact, this is what I teach. Three baptisms. Water baptism(turning away from evil and toward God, preceded by confession of sin) baptism of the Spirit(which is being born again) and baptism by fire (which is the refinement of our faith through trials)
Daniel 12:10 Many will be purified, made spotless and
refined,
Psalm 66:10 For you, God, tested us; you
refined us like silver.
Zechariah 13:9 This third I will put into the fire; I will
refine them like silver and test them like gold. They will call on my name and I will answer them; I will say, ‘They are my people,’ and they will say, ‘The Lord is our God.’”
This verse is talking specifically about trials and hardships (read the chapter if u don't know it)
1 Peter 1:7 These have come so that the proven genuineness of your faith—of greater worth than gold, which perishes even though
refined by fire—may result in praise, glory and honor when Jesus Christ is revealed.
Revelation 3:18 I counsel you to buy from me
gold refined in the fire,
