The account of Jesus giving his friends breakfast on the beach after his resurrection is a great one to look at with children - there's so much in it: lots of feelings, lots of drama, lots of Jesus showing how much he cares, and of course, lots of food.
Mark began as a secret follower of Jesus and ended up going on the first missionary journey with his cousin Barnabas and being commended by Paul. This could be used as a storytelling outline at an all-age communion service.
This simple outline offers a lively way to tell one incident from the Last Supper and introduces Jesus as the Saviour King who shows us the way to serve others.
