How would it be possible in 1,000 years to resurrect and educate the billions now in the grave?
Nevertheless, an illustration reveals what a simple, practical thing Jehovah has in mind for mankind. Not to prophesy, but merely for the purpose of illustration, let us assume that those who compose the “great crowd” of righteous persons who “come out of the great tribulation” on this system of things alive (Re 7:9, 14) number about 6,000,000 (about 1/1000 of earth’s present population). Then if, after allowing, say, 100 years spent in their training and in ‘subduing’ a portion of the earth (Ge 1:28), God purposes to bring back three percent of this number, this would mean that each newly arrived person would be looked after by 33 trained ones. Since a yearly increase of three percent, compounded, doubles the number about every 24 years, the entire 20 billion (20,000,000,000) could be resurrected before 400 years of Christ’s Thousand Year Reign had elapsed, giving ample time for training and judging the resurrected ones without disrupting harmony and order on earth.
