The narration between the second and third prediction of Jesus’ suffering in Matthew's Gospel (Matt 17.24–20.16) can be entitled ‘The life and the acting of the disciples in the light of the Kingdom of God’. The last part of this section is the parable of the workers in the vineyard. Although there are quite different proposals for defining the function of this Kingdom of Heaven Parable, its specific function in the narrative development of the basileia-line in Matthew's Gospel has not yet been the focus of the interest. The article at hand tries to close this gap by analysing the basileia-sayings in Matt 17.24–20.16 and exploring in detail the function of the Vineyard Parable in this frame. Special attention is paid to the examination of the interrelationship between divine and human action.
