The 'tell the gospel story' part simply means to convey the story from the Gospels, especially the story of Jesus' birth. It's like passing on the good news of that holy event.
The Gospel of Mark doesn't have as much of a traditional Christmas story as the Gospel of Luke, for example. But it does tell of Jesus' ministry which is related to the significance of Christmas. Jesus came to bring salvation and his teachings in Mark show his power and purpose. He healed the sick, cast out demons, and preached about the Kingdom of God. All of these things are part of the greater story of why Jesus came to earth, which is commemorated at Christmas.
One such hymn is 'Amazing Grace'. Its lyrics beautifully convey the concept of redemption and God's love. The lines like 'Amazing grace! How sweet the sound, That saved a wretch like me!' are very powerful in telling the gospel story of how a sinner can be saved through grace.
In the Gospel Christmas Story, the main event is the birth of Jesus. Mary, a virgin, was visited by the angel Gabriel who told her she would bear God's son. Joseph, her betrothed, was also visited in a dream and was reassured to take Mary as his wife. Jesus was born in Bethlehem, and shepherds in the fields were visited by angels who announced the good news of the Savior's birth.
The Mark Gospel doesn't focus as much on the Christmas story as, say, the Luke Gospel. However, it does talk about Jesus' life and ministry which is related to the significance of Christmas. Jesus' coming is central to Christmas, and Mark shows his power through healings and teachings.
One way is through personal testimony. Share your own experiences of how the gospel has changed your life. For example, talk about how it has given you strength during difficult times.
One way is by using parables. Just like Jesus did in the Bible. Parables are simple stories that carry deep spiritual meanings. For example, the parable of the Good Samaritan. It tells a story of a man who helps another in need, and through this, it can convey the message of love and kindness as part of the gospel.
Well, to tell the gospel story through worship, you need to create an atmosphere of reverence and connection. Use visual elements like symbols and images related to the gospel. Also, have a passionate and engaging leader to guide the worship.
