IF THE SALT HAS LOST ITS SAVOR ...

You might be shocked to know the real secret and origin of this parable! 
Mat 5:13  Ye are the SALT of the EARTH: but if the SALT have lost HIS SAVOUR, wherewith shall it be SALTED? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.

Isa 41:21  Produce your case, says YAH; bring forth your strongest counsels, says the King of Jacob.  22  Bring them forth!  Show us what SHALL HAPPEN: let them show the FORMER THINGS, what is that BE, that we may CONSIDER it, and know the LATTER END of them! or declare to us things to COME. 23 Show the things that are to come HEREAFTER, that we may know that ye are godly: yea, discern good or evil, that we may be dismayed to behold it together. 24  Behold, ye are of NOTHING, and your work of NOUGHT: an ABOMINATION is he that chooses you. 25  I have raised up one whose ways you did not know. He shall come: suddenly like the RISING of the SUN. He be called by MY NAME: and He shall come upon princes as upon mortar, as a potter TREADS clay. 26 WHO PROPHECIED it from the BEGINNING, that we may know? and BEFORETIME, that we may say, He is RIGHTEOUS? yea, there is NONE that shows, yea, there is NONE that declared, yea, there is NONE that heard MY words.

Mat 5:13  Ye are the SALT of the EARTH: but if the SALT has lost his savour, with what shall YOU and the EARTH be SALTED WORTH PRESERVING? It is thenceforth good for NOTHING, till CORRUPTION be cast TRODDEN DOWN under FOOT of a MAN.
