Quite simply: it does not apply.
It is a completely unscriptural perversion of the natural and obvious meaning of what Jesus said.
The Watchtower are despicable frauds who have willfully twisted Jesus words to fit their self-serving 1914 false doctrine.
And the deluded 8 million Watchtowerites who support and perpetuate this blatantly false creed simply have no common sense or love of truth, preferring unquestioned loyalty to the Watchtower idol than the words of Jesus.
