you might not know sin but you would still do it. with the commandments also came the blessing that if we confess and repent of our sins Jesus will forgive and heal us.
fire???? the fuel is the fruits of the flesh:
Galatians 5
19 Now the works of the flesh are evident, which are: adultery,[c] fornication, uncleanness, lewdness, 20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, 21 envy, murders,[d] drunkenness, revelries, and the like;
the world just burns with those evils.
