Was Paul speaking of baptism of water... or baptism of fire (spirit)?
(As John the baptist said, "I baptize you with water for repentance... but after me will come one who is more powerful than I, whose sandals I am not fit to carry. He will baptize you with holy spirit and with fire..." Matthew 3:11)
Born again IS all about Baptism.
John the Baptist explained that baptism will cause divisions. The wheat from the chaff:
The fire is for the chaff! (it is not the spirit)
That one will baptize YOU people with holy spirit and with fire. 12 His winnowing shovel is in his hand, and he will completely clean up his threshing floor, and will gather his wheat into the storehouse, but the chaff he will burn up with fire that cannot be put out."
Jesus Christ himself explained more about the effects of the fire:
"I came to start a fire on the earth, and what more is there for me to wish if it has already been lighted? 50 Indeed, I have a baptism with which to be baptized, and how I am being distressed until it is finished! 51 Do YOU imagine I came to give peace on the earth? No, indeed, I tell YOU, but rather division. 52 For from now on there will be five in one house divided, three against two and two against three. 53 They will be divided, father against son and son against father, mother against daughter and daughter against [her] mother, mother-in-law against [her] daughter-in-law and daughter-in-law against [her] mother-in-law."
The Wheat from the Chaff!
The most profound situation occuring on the earth today which can cause such family division is the disfellowshipping and then shunning of EX-Jehovah's Witnesses.
It is all about his baptism!
