Some people take the God of Jews and Christians to task because the world he is said to sustain runs over, like a river in flood, with acts of aggression. Why doesn’t God do something about it, since he can? The question comes up often in the Bible. It is a question that believers pose, if in fact they are believers. Jews and Christians know this, if they have read the Torah, the Psalms, the Prophets, and the books of Job and Qohelet.
It is not a question non-believers necessarily pose, unless they want to aggravate believers. Ayn Rand atheists in particular are convinced that God does not care, and neither should they. Live and let die.
An ethically responsible way of approaching the question of God’s justice is to turn the question against ourselves. For example, why don’t we do something about human trafficking, since we can?
