Matthew 5:13[ Salt and Light ] "You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.
Salt acts as a preservative, in the case of what the Lord is saying above, true Christianity "should" be keeping the rot out of the world, however if there is less and less true salt more rot will be evident in the world.
Look at the world today, I see millions and millions of so called christians running around praising some Jesus (evidently not the one in the Bible) and yet the rot and stench of this world is rising to the heavens, WHAT DOES THAT TELL YOU? Most of the salt has lost its saltiness, what's masquerading in today's world as christianity is an apostate lie.
Come out of the babylonian whore brothers, lest you share in the judgement coming down on her...
