Millions of Witnesses believe in "new scrolls", based on the following "spirit directed teachings";
"W ill Jehovah use his holy spirit in the coming new world? That spirit will be the force behind the new scrolls that will be opened at that time". w104/15p.11par.17
"During this thousand-year judgment period, Jehovah evidently will give additional instructions, unknown to us at present, as new "scrolls" are opened". w856/15p.18par.21
"There will be an extensive educational program under the direction of the King Jesus Christ and his 144,000 corulers. New "scrolls" will then come into use. klchap.19p.185par.13
"But during the resurrection, countless millions of studies, based on the Bible and the newscrolls, will no doubt be conducted!" rechap.41pp.299-300par.15
These "understandings" are interpolations(to alter a text by the insertion of new matter, especially deceptively or without authorization)
of Revelation 20:12. Neither the terminology nor the "explanation" appear in that verse. Those who espouse the above and those foolish enough to be deceived by them, deliberately ignore Jehovah's personal warning at Revelation 22:18,19, "If anyone makes an addition to these things, God will add to him the plagues that are written in this scroll;and if anyone takes anything away from the words of the scroll of this prophecy, God will take his portion away from the trees of life and out of the holy city, things which are written about in this scroll".
Take this warning seriously and "test the inspired expression to see if it originates with God" !
