Let your Kingdom come. Let your will take place, as in heaven, also on earth.—Matt. 6:10.
Christendom generally does not teach the Scriptural truth that one day obedient humans will live forever on earth. (2 Cor. 4:3, 4) Today, most religions in Christendom teach that all good people go to heaven when they die. It was different, however, with the small group of Bible Students who were publishing the Watch Tower in the late 1800’s. They understood that God would restore Paradise on earth and that millions of obedient humans would live here on earth—not in heaven. However, it took time for them to discern clearly who these obedient humans would be. "
Here is the real WT origin of the earthly class.
This doctrine of an earthly "hope" was first introduced by the president of the Watch Tower Bible and Tract Society, Joseph F. Rutherford, on Friday, 31st May 1935, to an audience of Jehovah's Witnesses in Washington, DC, America. It was then published in a two-part article entitled "The Great Multitude" in The Watchtower, 1st and 15th August of that same year. The information presented was a change to the previous teachings of Jehovah's Witnesses. Their founding president, Charles T. Russell, had taught that the "great crowd" (or "great multitude") had a heavenly hope. That was the accepted teaching for over fifty years. When Rutherford became the president of the Watch Tower Society in early 1917, at first he continued to preach a heavenly hope for the "great crowd". This new doctrine, therefore, was not just "a different gospel" to the ear of a Christian; it was also different for all Jehovah's Witnesses.
