When Matthew Calmes was diagnosed with a brain tumor at the age of twenty-six in 2006, his world, and that of his family, was turned upside down. In Joy in the Sorrow, author Sara J. Hoffman, Matt's sister, shares his story and how his journey helped strengthen her relationship with Christ and define the purpose for her life. She tells how through prayer and a relationship with God, we can use Satan's tactics for God's good. Hoffman shares her testimony of the beautiful tapestry God created throughout Matt's journey with brain cancer and afterward. She shows how God uses people, nature, and signs to give hope, comfort, and joy in the midst of sorrow. Joy in the Sorrow exemplifies how we are all interconnected in this earth journey and made by God for God and his higher plans and purposes. It's a story that offers believers and unbelievers hope during their trials and sufferings.
