Theres a book (based on a sermon series) by Leslie Weatherhead that addresses this "Will of God" issue directly.

If you struggle with this issue, or want to think about "Bad things that happen to Good People" I suggest you find your local christian book store, or amazon and give it a read. Our Mens group focused on it a few years ago and I found it quite interesting.
