We've seen time and again that wizards survived attacks that would have killed a nomral Human. Aperently great magicl power also comes with great resilience.

Thus Jose - one of the ten wizard saints - surviving a Fairy Law doesn't mean all the non-mages and badly hurt Fairy Tail wizards (who were much weaker than Jose to begin with) would have survived Laxus' Fairy Law if it had fired properly.
