Our world is full of evil and suffering because God, our creator, plans to make us experience it. He's preparing us for eternal happiness and harmony. To appreciate it, we must first experience suffering and evil. (Read the Gospel and the Bible; then, you'll know.) God loves us immensely. He'll raise us from death. He's created a new and better world for us. Tell him all your problems. He's helped me a lot. He can help you, too.
