Hey that's a good question for a Christian!!! Yes, every disaster can become an opportunity for growth!
Think about the disaster that happened in Haiti with their huge earthquake. It's true they haven't been able to recover yet or completely or rebuild much at all, but many have learned to trust in Jesus, the author and finisher of true life. They have learned to sing and to praise God and the Lord has given them peace, love, and joy! And when they die they will go to heaven to be with our wonderful Lord forever!
So, it is well worth it if this is the only thing that will bring you around to reality. Jesus is Lord!

John 12:24-25 (GOD’S WORD Translation)
