This beautifully-illustrated hardback book by well-known singer and TV presenter Randall Goodgame is based on the parable in Luke 12 v 35-38.
It teaches children that Jesus will return, and when he does, there will be an amazing party where... SURPRISE!... he will serve his faithful servants!
Jesus didn't tell us when that party will be, but we can make sure that we're ready for it by loving him and loving his people while we wait.
