A story is told about a horde of locusts that devastated certain parts of South Africa. The landowners did everything they could to prevent the locusts from eating their crops, but all of their efforts were useless. The feasting of the locusts had completely devastated the land.
Shortly afterwards, something amazing happened. The horde of locusts died, and their bodies were plowed into the land. In a twist of absolute irony, the bodies of the once destructive locusts became the fertilizer that produced the best crops the farmers ever had.
In like manner, our tragedies—though devastating and destructive—often contain a hidden potential for growth. Just as winter is essential for summer, tragedy is essential to an eventual triumph.
