13“You are the salt of the earth,(A) but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people’s feet.
Through guarding ones chastity one maintains ones virtue, ones virtue in the case of males is semen. In the above passage Jesus is referring to loss of semen when he speaks of the salt of the earth losing its taste. Men who spill their semen on the ground are like salt that has lost its taste. The reason for this is that semen is virtue and when men lose their semen they lose their virtue.
Above is a link to a list of people who died early deaths who happened to have been exploited by pornography companies and thus were known as “porn stars”. The above link is an example of people who were “thrown out and trampled under people’s feet”. And they were also people who spilled their virtue on the ground instead of guarding it through chastity.
