Sending a Messenger nearly 2000 years in advance to preach the coming of God’s Kingdom, and leaving the message to be carried out by his followers who would practice just the opposite of his message [eg. Catholics cannot accept a Pope if he is from a Black community or if sex is female, just like JWs could not tolerate a Black/woman WT President, which is in sharp contrast to what Jesus himself practiced—he showed no partiality with regard to sex or community—he elevated a Samaritan woman sharing with her great truth, even before he did it with his own male-disciples—John chapter 4]. Claiming something as His own, and then allowing it to decay do not befit God’s superlative style!
Logic suggests that message about system change should happen in the last generation, after which New World would start! Interestingly, this is the style adopted in the Eastern Scripture (Bhagavt Gita 4:7) Bhagavat Gita is the summarization of all the other Hindu scriptures. According to Gita, God of the universe take measures only in the last generation of Human Rule—when the irreligiousness and moral decline reach their climax, and when humans themselves destroy each other—and then He recreates Heaven on earth (which people are free to maintain it or to reshape it into Hell again)!
