Some before-and-after stories are positive and inspiring, and some are negative and heartbreaking. While some people experience changes in their lives that bring them more success or comfort or better relationships, other people experience changes that create disharmony and heartache, especially when they make hurtful and self-destructive choices. The story in scripture about a man named Demas is a painful before-and-after story that reminds us that some personal transformations aren't always joyful.
