31 “For this reason I say to you, every sort of sin and blasphemy will be forgiven men, but the blasphemy against the spirit will not be forgiven. 32 For example, whoever speaks a word against the Son of man, it will be forgiven him; but whoever speaks against the holy spirit, it will not be forgiven him, no, not in this system of things nor in that to come. (Mt 12:31, 32)
The fire has been lit, you need to figure out which fire, 1 or 2:
#1 “I came to start a fire on the earth, and what more is there for me to wish if it has already been lit? 50 Indeed, I have a baptism with which to be baptized, and how I am distressed until it is finished! 51 Do you think I came to give peace on the earth? No, 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 mother, mother-in-law against daughter-in-law and daughter-in-law against mother-in-law.” (Lu 12:49-53)
#2 “The tongue is also a fire. The tongue represents a world of unrighteousness among our body members, for it defiles all the body and sets the whole course of life on fire, and it is set on fire by Ge·henʹna. (Jas 3:5, 6)
To get my young children interested in physics, I used the old "generate static electricity with a balloon", experiment.
I explained what static electricity was and rubbed the balloon in my hair ( I had hair ... then), until the hair stood up on end. and went over to a wall with the balloon, and had my head stick to the wall.
