Free will or not?

Some people deny the need to change habits that may harm their personal health by asserting that it's God's will how long they will live. They also deny the need to change habits that affect the environment by invoking God's will. I notice that when they want a job, they don't wait for God to provide them with one; they take personal responsibility. They look at want ads, etc., and fill out application forms.

Similarly, some people are claiming God is punishing the world by various natural calamities, including tsunamis and hurricanes. But when a bus carrying children to or from church camps is in an accident, killing and injuring the children, or as recently happened, a little girl who was walking to church was killed by a car, nobody is such a jerk as to ask what God is trying to tell people.
