I am not just believing this faith of good news of the new world, but already living this faith. For me new world is not just a promise to be realized in the future; I have made it a reality in my mind. There is no need for external permission for this purpose: every individual can enter into this state by his own decision. I take every incident at which people usually get offended as normal and adjust to it, just as all situations, both pleasant and unpleasant, are accepted within a family. I just universalize this family culture wherever I go, thus making my life already in a new world.
This reminds me of a film I saw where a guy goes on holiday to Mars in his mind.
And no wonder. What good news they have to tell the people! They proclaim the good news that the millennial rule of Christ will begin with this generation and that it will mean ever so many blessings for the people :..Watchtower June 1 1968 page 331
This Watchtower quote is talking about Matthew 28:19,20 which Jehovah's Witnesses were carrying out this commission at the time in 197 lands and islands.
the good news of the millennial rule of Christ is the thousand year reign of Christ not something taking place in your mind.
This occurs after Har-Magedon, Revelation 20:1-3 and not as part of it according to God's Eternal Purpose Now Truimphing for Man's Good page 186
As far as I know this has not taken place and the teaching has been changed on the defining of the generation.
