We can't blame on bad luck
Then, when the farmer's son was attempting to tame one of the wild horses, he fell off its back and broke his leg. Everyone thought this very bad luck. Not the farmer, whose only reaction was, "Bad luck? Good luck? Who knows?"
Some weeks later, the army marched into the village and conscripted every able-bodied youth they found there. When they saw the farmer's son with his broken leg, they let him off. Now was that good luck or bad luck?
Who knows?
Everything that seems on the surface to be an evil may be a good in disguise. And everything that seems good on the surface may really be an evil. So we are wise when we leave it to God to decide what is good fortune and what misfortune, and thank him that all things turn out for good with those who love him.
