I am thankful for fellow Christians. They can make awesome games (such as the Aetherlight), write books, and much more. It is easy to feel alone as a Christian when the whole world seems like it disagrees with you, but we are never alone and it is comforting to see and hear others who are also following Jesus. Though many things threaten to divide us, we can be united in our core values and the joy of the gospel.
Also, reading what fellow Christians are thankful for brings positivity and reminds me what is important.
