It's a very hard question to answer,why bad things happen to good people.The answer will not be fully understood until the next life but He gives us a few hints.I believe that HE gives us trials to strengthen us and also to help grow.Bad things happen to everybody that is how HE is a just and fair God.Remember faith always precedes miracles, and miracles do happen.Now things don't always turn out the way we like, but there is a lesson to be learned. My prayers are with you,and especially your brother-in law and his family.
