the good news is ( will) being preached in all the earth, and then the end will come....
Since the number of people in the world keeps on growing the good news will never ever end and it is assumed that neither will the gospel's true message.
The Good News that JWs preach if you can call it that has never reached more than 2/3rds, if that, of the Earths population.
If as they have stated before it is only a witness to the Nations and not every living soul on earth,can you imagine what paradise would be like with over 1 billion Muslims being resurrected ?
{ because they have never been witnessed to in strict Muslim lands }
Their would have to be an end to child birth to occur ,and for those already born to reach a mature age if every human soul was to receive a witness and make a decision to obey God or not.
Obviously that`s not going to happen.And neither what Jesus Christ predicted either .
Remember Jesus Christ was coming quickly in Revelation and that was over 2000 years ago.
