There are two quite distinct teachings in this short 6 verse section from Matthew 18: the teaching on resolving arguments and the teaching on corporate prayer. To capture both, this retelling weaves a fictional story about one of the crowd of extra’s. We know from Acts 2 that many men were with Jesus throughout his time but not chosen to be one of his disciples, one called ‘Justus’ is mentioned and this is an imagined story of his. Which of the two elements you decide to stress is entirely up to you.
