I also do dot agree with the explanations.
I believe the growth of the leaven in three parts, means that Christianity grew through different christian religions and organisations.
I also don't believe in the explanation in next week's article about the fish-men who catch good and bad fish. I think the real separation will be at Armageddon and the judgement will be individual.
I believe the illustrations discussed in the 2 articles show that the message on the kingdom of god grows through different christian religions and organisations and in the end the judgement and the salvation will be individual.
I also believe the explanations are "forced" just to fit into our general believe that the JW's are the only religious organisation approved by God.
They are doing what they say in the beginning of the first article we should not do if we want to understand the meaning.
PS: English is not my fist language, please excuse my mistakes, if they exist.
