Matthew 5:13
Matthew 5:1313You are the salt of the earth. But if the salt loses its savor, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.
JWs read "you are the salt of the earth" devotionally as a call to preserve righteousness in a corrupt world. The Watchtower's framing emphasises that Witnesses preserve truth precisely because they remain separate from the world's corruption — salt's preservative power is read as parallel to the organisation's role as a faithful remnant. The verse rarely appears in JW publications paired with Jesus' "do not take them out of the world" prayer in , where the implication of salt's mode of operation becomes uncomfortable for the categorical-separation reading.
Salt only preserves by contact. A salt cellar on the shelf, sealed away from the food it is meant to save, is useless — Jesus says it is fit only to be thrown out and trampled underfoot. The metaphor's structure rules out the categorical-withdrawal reading: the whole point of being salt is being IN the meat. Read with ("I do not ask that you take them out of the world") and (a city set on a hill is visible BECAUSE it is in the geography), the Sermon-on-the-Mount image of Christian witness is one of saturation contact, not separation. The Watchtower's withdrawal pattern produces exactly the salt-cellar scenario Jesus warned against.
