The narrative and programmatic significance of both “preaching” and “casting” indicate that the content of the to preach(v. 14c) component of the Mark 3 commission is the authority to cast out the demons (v. 15). This is grammatically and syntactically allowable and is affirmed by how Mark crafted his narrative. Reading the commission in this way challenges a narrowly defined, verbal- and cognitive-based understanding of evangelistic activities. As fisher-followers, the church’s paradigm for evangelism is found in the Mark 3 commission, which indicates that Christians and the Christian community should include evangelistic activities that confront Satan’s dominion over the realms of humankind and that reorient those realms to reflect the inaugural presence of God’s kingdom. Thus, the task of “casting” corresponds to any analogous obedience (i.e., application) that confronts what is contrary to God’s design for living in the land and that demonstrates how God’s rule affects the realms of humankind.
In order to move appropriately from text to application, there should be a correspondence between the meaning of the text, its significance to the readers/listeners, and the action taken that indicates obedience to the text. For the church in front of the text, the significance of the Mark 3 commission is our alignment with and commitment to the mission of Jesus (1:14–15) and to exercise Jesus’ authority through actions that demonstrate, concretely and evidentially, that God’s rule and reign has entered time and space. Certainly, as the whole of the NT indicates, evangelism includes proclamation (i.e., verbal- and cognitive-based activities of communication) that presents the information of the Good News, announcing and explaining that the kingdom is near. Yet, such proclamation is not the end of evangelism. Mark’s Gospel narrative as a whole and the Mark 3 commission specifically indicate there is also to be a resultant consequence of the “preaching,” another viable mode of language, namely the doing of deed-parables. As parables revealed the mysteries of the kingdom, deed-parables evidence (i.e., have outcomes that indicate) the undoing of Satan’s power over the affairs of humankind (Mark 3:27) and, as a result, seek to reorient people and the world back toward God’s rightful dominion (an underlying significance of the Mark 4 parable of the mustard seed, vv. 30–32).
Evangelism is the spread of the gospel, the seed sown (Mark 4), which according to Mark’s narrative is dynamically linked to the end of Satan’s dominion and the inauguration of God’s rule and reign. This is what biblical evangelism looks like: as Jesus’ “casting” action demonstrated the end of the strongman-Satan’s kingdom and the arrival of God’s kingdom—visible and evidential acts that indicate the time has been fulfilled and the kingdom of God has come near (1:15a, author’s translation)—so, for the church seeking to obey this text, the significance of the “casting” component of the Mark 3 commission is the continuation of Jesus’ mission to confront the powers that oppose God’s dominion. Therefore, as indicated by the fisher-promise’s association to OT contexts that include the issues of poverty and, as well, the implications of the Mark 12 poor widow episode (12:38–44), applications for “casting” should include advocating for those affected by poverty.
Separating social action from evangelism is an unwarranted dualism
As I demonstrated in chapter 3 (“You Will Appear as Fishers”), the Mark 3 commission is the inaugural fulfillment and premiere application of the Mark 1:17 fisher-promise. The fisher role is related to God’s judgment and action toward people and structures that distort God’s creation from his design and reign over it, which includes advocacy for those affected by the issues of poverty and injustice. This allows evangelism, that is, the sowing of the word/gospel to also include the realm of social action, which demonstrates God’s rule and dominion over the realms of society and people that impact the poor and economically vulnerable. This is supported by antecedent OT material related to the economically vulnerable that is associated with the judgment role of fisher-followers. This implies that the Mark 3 commission (3:14–15), to some extent, should be associated at the application level with social action, which is legitimate obedience for following Jesus Christ and for being faithful to the gospel. Therefore, obedience to the Mark 3 commission includes “applications, activities, and outcomes of social action and justice”[x-ref] that should be an intentional component of a church’s or Christian community’s evangelistic activities, which is, at least in part, the fisher-follower’s task.
The obedience (i.e., application) and the desired outcomes analogous to the purpose and intent of the commission to have authority to cast are those which demonstrate God’s reign and rule. Separating social action from evangelism is an unwarranted dualism that is alien to the gospel as Mark presents it in his narrative and, as well, to the wider biblical record. As proclaiming the kingdom’s arrival was demonstrated by Jesus’ deed-parables (i.e., castings, healings, miracles), the evangelistic task of the church is to include analogous activities that indicate the presence of God’s rule and reign. This also makes redemptive-historical sense of the authority to cast out the demons (Mark 3:15) as a display of the all-encompassing arrival of God’s kingdom: God in Jesus Christ has reconciled all things to Himself (Col 1:20) and with a view to an administration suitable to the fullness of the times, that is, the summing up of all things in Christ, things in the heavens and things on the earth (Eph 1:10).
Social action that reflects God’s design for living in the land—social action, that is, that demonstrates his reign and his righteousness that is to be expressed among people—is the responsibility of faithful fisher-followers of Jesus, God’s Messiah-King. Consequently, evangelistic activities of the church ought to seek to ensure that the economically vulnerable and the poor (i.e., the land-less) are full participants in the benefits of living in the land. In other words, as Mark’s narrative richly portrays the gospel of Jesus Christ (Mark 1:1), social action outcomes should be included as a component of a church’s task of evangelism.
 Note the final discussion on this parable (i.e., the mustard bush) in chapter 2, “Wasted Evangelism.”
 Refer back to chapter 1, “Widows in Our Courts,” for a biblical illustration how both people and systems can cause others to live with the effectsof poverty; additionally, review the OT texts that juxtapose idolatry with poverty in chapter 5 (“Idolatry and Poverty”).
 This is the argument of chapter 3, “You will Appear as Fishers.”
