I know people who like to argue (or "better understand" to put it charitably) will run to their Bibles to look for passages about how people's days are numbered etc. They will say, "See! The Bible says each person's days are numbered and their time is up!"
Listen, again, I am trying to orient you back toward wise reading of those passages, rather than defensive and agenda driven reading of them.
What would I say, if I was a pastor, talking to this family? I would say "God is in control" rather than "It was God's will that her time was up." "God is in control" is the more accurate Christian contemporary type of abbreviated condolence saying because it is not targeted on the death of the person herself. "God is in control" of everything, which means the dispensation of all people and agencies involved at all times. God does not focus his will or control on just one person's accidental death. God is in control of the ultimate outcome of all of human beings' own actions. God makes all things good; God does not make the errors. So to comfort a family you tell them that God is in control, assuring them that justice, mercy and blissful joy will be awarded to even those who suffer at the hands of deliberate or accidental cruelty and loss by other humans.
That is the meaning that all days are numbered, which is there are limitations, and God in his all knowing knows in advance what people will do to each other, and the number of days each person has before age, mishap or illness catches up with them. It's a totally different meaning than God winding up some clock for each person! Gosh I hate that New Age thinking. God knows and foresees all that happens and it is "his will" that it takes place because he does not intervene, in general, in how humans manage themselves. He is not disinterested, and the Holy Spirit works tirelessly to convert and bring everyone to more charitable and responsible behavior, for the glorification of God and for the survivability of humanity. So no one can accuse God of being some detached blob of "universal energy" "detached" and "not caring" about what goes on with individuals, each of whom, truth be told, he knows in their very soul and cares about deeply.
People keep forgetting about guardian angels too. They are not guardian angels in the sense of throwing themselves in front of irresponsible drivers to save their charges from disaster. They are, though, the voice that whispers "Don't drink and drive" and "Put on your seat belt" and "Care about your neighbor." Guardian angels are just one proof that no human lives, or dies, alone. Remember that when this lady in the car hit and run died, her guardian angel went to see God with her. That's an uncaring God? Get over yourselves, please!
Now, Muslims often use the expression "It is God's will." They will say it at times like this, such as tragically losing a family member. But they really are saying "God is in control" because when they say "It is God's will" they are not saying "God did this to her," but they are confessing their knowledge that God is in control of everything, and that events like this fall within his universal control and will. Again, this is a broader and thus more theologically accurate statement than what Christians have come to mean in these personally obsessive and "God limiting" phrases and observations. So when a Muslim says "It is God's will (that a person died)" they will not claim that they know what God is planning or thinking, or even how God perceives humans at all. They mean "God is in control and it is his will that events like this do happen (because he has given life to humans and life does have sorrow and loss by definition.)" Muslims, no matter what sect they are, have a firm and accurate perception of God that God is unknowable and has a much more vast scope of control and perspective than humans could ever have, and that no one event or human life can be interpreted as being a humanly understandable example of his taking action. It is God's will but it cannot be claimed that a human understands what, if any, action God is taking in a human life or event. Only Christians and others who think they can cut God down into understandable parcels think like that. Muslims don't.
I hope this helps. My next blog posting touches, actually, even though I wrote it earlier this morning, on an extreme example of where people need to better understand how they cannot characterize God's will in any correct or understandable way.
