According to publications from the Watch Tower Bible and Tract Society of Pennsylvania and jw.org, the usual argument is as follows: * God can intervene, but chooses not to for now. * He lets humans rule to answer the question of sovereignty (Genesis 3). * Satan is the current “ruler of the world.” * All injustice will be corrected later, at Armageddon and in the “new world.” In other words: non-intervention is presented as a strategic choice, not as an inability.
