Sovereignty is the quality of having supreme, independent authority
The way I see the issue of Evil vs God's Sovereignty is this.
You either HAVE Sovereignty OR you do not have it.
If you have to wait for approval of others (proving you deserve it, for instance) then it is the "others" who are GRANTING the Sovereignty.
It becomes an elected office, so to speak.
If you really ARE Sovereign it is a FACT that "others" must deal with. That would include evil others.
Allowing Evil is an act which ABANDONS Sovereignty to chaos or debate.
I am strongly convinced the mythos of Scripture is a work-in-progress as far as defining or explaining the role of Deity in dealing with Evil and Suffering.
The best the ancient Jews could come up with is this: If we suffer Evil we must deserve it. So, that succeeds in letting God off the hook morally.
It was a question of "deserve".
This did not solve the problem of infants and the innocent.
So, the theology of "original sin" had to be imputed to infants and no truly "innocent" person could enter the equation.
But, allowing "evil" from sin to infect humanity didn't seem so great either.
So, GRACE was invented. But, to make God morally superior in granting GRACE humanity could not be seen to "DESERVE" it.
Christianity is a passive experience. You just have to embrace the seeming Sovereignty of God without earning it.
Yet, even with the salvation of Christ the evil and the suffering continues. It is a storybook victory over Evil.
What destroys, for me, the illusion that a Sovereign God exists is the presence of Evil and Suffering.
There is no morality to a God like this.
Permission for evil is the motor that drives the suffering. It is a compact.
In any compromise between food and poison the one eating suffers the result.
What Chef would permit one of the cooks to add poison to a meal and yet pretend he was in no way complicit simply by disapproving without STOPPING the serving of the meal?
Permitting the poison of evil in any way is to commit murder.
If we want to believe in a God who is a murderer we might want to rethink our alternatives first.
