Excerpts that may apply:
God is not only more powerful than any evil-doer, he can take the worst evil and use it for the highest good. Overstatement? No. Was the crucifixion the greatest evil ever committed by Satan and fallen man? Yes. Was it ordained by God to produce the greatest glory for God and the greatest good for men? Absolutely. We can't figure out how that works. (Why should be expect our finite minds to understand the workings of the infinite God? Isaiah 55:8-9) Fortunately, our inability to understand how it works never diminishes the sovereignty of God.
Isaiah 55:8-9 (Holman Christian Standard Bible)
8 "For My thoughts are not your thoughts,
and your ways are not My ways."
[This is] the LORD's declaration.
9 "For as heaven is higher than earth,
so My ways are higher than your ways,
and My thoughts than your thoughts.
A more biblical analogy, I think, is that we have true freedom to walk the ship, to choose when and where we eat, whether or not we befriend other passengers. We can do good or evil. We can stay on the ship or even jump overboard. But we do not have control over exactly where the ship is going, the sway of the sea, the weather—sunshine or storms—and whether we ultimately live or die. Some things are determined, even when we don't know the timetable, our death among them
("No man has power over the wind to contain it; so no one has power over the day of his death," Eccles. 8:8).
Using the illustration of the ever-popular Titanic, these people were free to make meaningful choices, both moral and immoral, and indeed they did so. They were not free, however, to snap their fingers and go back in time, causing the ship this time to miss the Iceberg. Nor were they able to keep the Titanic from sinking, no matter what they did. You and I can't make this world into something that will avoid its inevitable destruction by fire (2 Peter 3). But we can certainly help the needy, bring the gospel to the lost, feed the hungry one at a time, pray and serve our God in meaningful choices each day.
God says "I am the Lord, and there is no other. I form the light and create darkness. I bring prosperity and create disaster; I, the Lord, do all these things" (Isaiah 45:7). Our tendency is to try to be God's PR people by absolving Him of all disasters. Sure, we can link them to the curse on the earth due to the sin of man, and yes demons do seek to bring disasters on us, but by distancing God from disasters (in a misguided attempt to defend his goodness—which needs no help from us) we end up with a deistic God who just lets the universe go wherever it will, run amok because of our sin. That kind of God isn't vitally involved in our lives. He does not work all things together for good, like the true God of the Bible.
We are right to try to distance God from the commission of evil—Scripture does this—but we are wrong to distance Him from being sovereign over evil. Spurgeon suffered from a very painful malady and said something like "If did not believe God sent me this affliction, I would despair." Being an insulin dependent diabetic was orchestrated by God to increase my sense of dependence on him. Being sued by an abortion clinic for 8.4 million dollars was orchestrated by God to take me out of a pastoral ministry I loved to do what He really wanted me to do. God's hands weren't tied by my genetic propensity toward my disease (result of the curse), nor by the vengeance of child-killers (result of human sin and demonic strategy). He didn't merely "make the best of a bad situation." He took a bad situation and used it for His highest good. So much so that I can no longer think of it as a bad situation—it was a severe mercy, a grace disguised in hardship.
If this were not true, a woman who lost her husband would have to believe that she had experienced bad luck, that God is either not as powerful or not as loving as He claims to be. The couple whose 16 year old daughter was killed in a tragic car accident would have to believe that her death was a cosmic accident, and wouldn't have happened if only she hadn't been at that place at that time or if others hadn't been on the road or if only this or if only that. We can drive ourselves crazy with this. But embracing God's higher purpose in events that are painful and even tragic is an affirmation of God's greatness. This is not fatalism. It is faith in the promises and character of God.
It seems to me that God is in control over all, everything. That some things I can understand, some things I will never understand.
