"The disciples' mission (vv. 7-8) replicates and extends the mission of Jesus in preaching the coming of God's kingdom and in healing the sick (see 4:23)" (Harrington 1982:45). Matthew emphasizes the continuity between Jesus' mission and that of the disciples precisely because the model of ministry God had exemplified in Jesus remains important for Jesus' followers (see more fully Wimber with Spring 1986:113-15; Keener 1996:85-89).

Insofar as possible, we should learn to demonstrate Jesus' rule the way Jesus did. Although hardhearted people may never be satisfied with signs (15:37-16:1; compare Jn 11:47-48; 12:10-11; Acts 4:16-17), signs can draw other people's attention to the gospel (Mt 11:3-6, 21, 23; see also Jn 2:11; Acts 4:29-30; 9:35, 42). If such ministry is more difficult in our rationalistic culture, it may be for that reason all the more important. Yet some parts of today's church that are open to miracles unfortunately have missed another part of Jesus' teaching on faith and mission: God's messengers must live simply (10:8-12).
