Inevitable Doom for Organized (Moral) Bodies?

[Raphael]

God created a perfect world, our world back then with its organized concepts of truth and perfection.. but then somehow it didn’t last long and ended in quarantine status due to moral, physical and environmental plagues. God then planted a small garden of Israel but the caretakers instead wanted to own it and killed the owner thus that garden was also inevitable lost. Then God maintained His presence in various bodies that all inevitable lost their ways, like the Catholic body.. then God made His presence through the Millerite movement that ended in catastrophic measures.. then God gave new guidance through the early SDA movement, particularly through EGWs visions that forms our current SDA body.. will this SDA God ordained body sooner or later end up like all works of God under the assailment of the dark, as well? (though as history shows, God keeps coming up with endless tactics to maintain his involvement in the game) Is there a study on this? Please share with us. Thanks.
