We are dealing with an entire system, a way of organizing reality in such a way as to ease the pain of present mediocrity by endlessly daydreaming of a deus ex machina reversal that takes place with no connection to their present efforts and experiences.
Since fantasy is a poor substitute for reality, it tends to have an escalating grip on the psyches of those who use it as a substitute for reality. Those who prefer 2-D colored dots to a flesh and blood spouse find that porn escalates its demands. Those who prefer end-times fantasies to present faithfulness continue to return, like dogs to vomit, to lurid speculations and "newspaper eisogesis."
Blessed are those who hunger and thirst for righteousness, for they shall be filled. In The Lion, the Witch, and the Wardrobe, Edmund is seduced by Turkish Delight -- a paltry but addictive substitute for his soul's REAL hunger ("Aslan" is Turkish for Lion). God's elect, with a real hunger for Him and His glory, eventually find trite substitutes nauseating and spew them out of their mouths in disgust. Hence the frantic desperation among dispensationalists -- they are defending a failed system -- and the traffic is only going one way. Many of us once sat where they sat, and thought as they did. Then, we got a taste of God's glory, of His wonderful purposes for our lives. Purposes that extended beyond the realm between our ears, and embraced objective reality.
IOW dispys have never had a taste of God's glory; Dispys have never had a taste of the wonderful purposes in their lives.
IOW preterists are better Christians and more spiritual than Dispys.
