In the biblical story where God destroys Sodom and Gomorra. Where he tells lot to leave the city and not to look back or he will be turned into a pillar of salt. I am beginning to see that this was not God be vengeful on Lot‘s wife when she looked back. . I know now it has some symbolic meaning about mourning for what can‘t be anymore. But why a pillar of salt? Salt in those days was valuable and used for currency. Maybe there is a theologies out there who can answer this one for me.
