According to WT dogma, the issue of universal sovereignty was supposed to have come into play in the Garden of Eden when Satan challenged Jehovah's right to rule.
Adam and Eve took Satan's side of the issue.
Man was then given so many years to come up with a workable alternative solution, which, of course, he couldn't.
So, it was left up to Jehovah to settle the issue when His Son, known as Michael in the heavens, was sent to earth to suffer and die, and was raised to heavenly life and placed on the throne to rule all Creation.
Convoluted?
You bet!
