If you believe in the Law of Attraction and are actively creating what you want, then you should not be attracting things like houses burning down.
However, I believe if things like that happen to you, you have to look for the opportunity to learn, no matter what the situation. It was put there because somehow you were on a wrong path in your thinking and the Universe is sending you messages so you can correct it.
I lost my most lucrative freelance contract last November and, while it scared me a little to be without the money, I looked upon it as an opportunity to pursue other things which are more in line with who I really am and my true passions. Altho this has not started to pay of in a monetary sense, I feel better and I truly believe it was a good thing for me to have that job end.
Once an event happens, it is over. Fear and depression won't undo it or change anything. You have to believe it was meant to happen for some reason and try and see what the reason was.
Many people lose a job and then find another better one and they see it was a good thing to have lost the first job. If you are making bad money decisions which lead to things like bad business deals, then you are not in a wealth consciousness which would lead you to make better decisions. People who live in fear and a scarcity consciousness will always have "crisis" happening to them and lose money.
