The world looks bustling and busy, but I see emptiness in the hearts of people all around. Facebook has over a billion members. In today's news, a study has shown that many Facebook users are lonely people and they feel even worse each time after using it. People keep busy just to forget or cover up their emptiness; they drift through life. Not being concerned about not knowing where they are heading is sad. Not knowing that Christ can completely fill their emptiness and change their lives is tragic.
