The WT illustration is used to answer the question, "Why has God permitted suffering for so long?" But here's another flaw in the illustration: It only takes a few minutes to answer a math question, so why hasn't God ended suffering yet? The Witnesses can study with someone for just 6 months and convince them that God has the right to rule. So why has it taken more than 6,000 years to prove it to the angels? Shouldn't they be smarter than mere imperfect humans? Just how dumb are they?
Also, wouldn't the passing of so much time just prove the opposite about God? If the angels have an ounce of morality, wouldn't they be sickened by watching God stand by as he allows his children on earth to beat, rape and murder one another as he does nothing? Is God really helping his case or hurting it?
Or are the Witnesses really blaspheming the Almighty, making him look stupid and impotent, by their use of such an incredibly inappropriate illustration? Let's see know, the choices are: 1) Either the angels are slow and stupid 2) God is an evil father to allow his children to kill each other 3) or the Witnesses are blaspheming God with an incredibly inappropriate illustration that is demeaning to God? Hmmmm... which is the correct answer?
