Finding "persons of peace" is an important element in most disciple making movements. This practice is grounded in Jesus' instructions to his disciples when he sent them out on mission. Jesus also led by example as this comparison table shows.
Much of Luke’s gospel is taken up with Jesus’ final journey to Jerusalem (Luke 9:51-19:28).
At the beginning of the journey Jesus sends the 72 out on a mission to the towns he is about to visit.
Near the end of Jesus' journey to Jerusalem he meets Zacchaeus the tax collector. In that story Luke gives us a detailed account of how Jesus typically entered an unreached community through a receptive household. Jesus did what he taught his disciples to do.
There are clear parallels with the instructions he gave to the 72 before sending them out on mission (Luke 10) and Jesus’ encounter with Zacchaeus (Luke 19).
