"The beginning of the gospel of Jesus Christ, the Son of God." - Mark 1:1
Mark wrote a "Gospel". As did Matthew, Luke, and John. The term literally means "good news". It means that Mark, as well as the other Gospel writers simply had a story to tell. Why is it that our anger keeps us from telling a joyful story sometimes? What keeps us from joyfully recounting the good news of our encounter with Jesus?
