All for the Best

Ultimately whatever happens to us is for our good. The Talmud relates a story about two people who wanted to travel by boat. One broke his foot and was unable to make the trip, while his friend got on the boat. The one who missed the boat cursed his misfortune. A few days later, however, he heard that the boat sank and all the passengers drowned. He began to praise the Almighty because he now realized his missing the boat was the best thing that could have happened to him.

A person should accept suffering that befalls him, since he cannot possibly know what good will come as a consequence of this ostensibly "negative" event.
