However, we must begin long before this mountain sending in order to understand the full scope of God’s mission in the world. Scripture tells a coherent story, from beginning to end, of the origins of creation in God’s mighty word to the telos of all things in the descending of the glorious New Jerusalem, the peaceable new creation, God’s dwelling with humanity and his shalom in abundance for all. After God’s pronunciation of “very good” on all creation and especially on humanity as made in the image of God, Genesis 3 tells the tale of the alienation wrought between humanity and God, between humanity and creation, among humans in their life together, and within each human person him or herself. The name for this alienation is sin, and as Paul would later say, “the wages of sin is death.” Murder, violence, pride, hoarding, and division ensue, piling upon one another as the world spins out of control, truly falling from a primal transcendence over—inasmuch as with and for—the rest of creation.
And yet! In Genesis 12:1-3 God calls Abram, promising to him innumerable descendants, a great nation and thus a great name, and (most importantly) that “all peoples on earth will be blessed through you.” By the calling of Abraham, God put into action what Lesslie Newbigin calls “the logic of election.” God would not reveal himself to all persons equally, nor would he be immediately present to every people or region of the earth—no, God would reveal his will, his law, his saving purposes through a people and thereby work his purposes for the blessing of all the nations. Thus—as Abraham’s son Isaac, and Isaac’s son Jacob, and the twelve sons of Jacob, and the twelve tribes proceeding from those lines lived and grew over time in Egypt, were enslaved by Pharaoh and brutally oppressed, only to be delivered mightily and publicly by the hand of Yahweh, the same God who called Abraham so long before—was Israel born, the holy people of God’s own choosing.
Israel was to be God’s “treasured possession,” a “kingdom of priests and a holy nation.” through whom God would bless all the earth. Over time, however—through taking the land, through the time of the judges, through monarchy, disobedience, exile, and return—Israel was perpetually forgetful of or unfaithful to its calling and vocation. Having been delivered anew from landlessness in Babylon, God’s people remained under occupation in its own land by a foreign power. Who would bring, when would come, how would look the final and definitive establishment of the righteous rule of the one God on the earth, in vindication of God’s people’s suffering?
“At that time Jesus came from Nazareth in Galilee and was baptized by John in the Jordan. ... After John was put in prison, Jesus went into Galilee, proclaiming the good news of God. ‘The time has come,’ he said. ‘The reign of God has come near. Repent and believe the good news!’” Jesus of Nazareth comes proclaiming the reign of God, but not only proclaiming, embodying: with healing, with forgiveness, with table fellowship and welcome for sinners and outcasts, with radical inclusivity for the marginalized, with subversive teaching and concrete resistance against both the religious and the political establishments of the day. Jesus calls Israel to be gathered around him, to follow after him as disciples—but discipleship to this Nazarene is no simple thing: “Whoever wants to be my disciple must deny themselves and take up their cross and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me and for the good news will save it.” Suffering, opposition from the powers, love for enemies, reconciliation, truthtelling, right worship, hospitality toward the other, peaceableness toward all, no care for possessions or for tomorrow—all these things and more would characterize disciples of Jesus as gripped and called forth by and in the reign of God.
Yet the powers that be could not stand by and watch this movement upend their plans. Jesus of Nazareth is crucified as a convicted criminal, condemned by his people and accursed by God, utterly rejected, naked and alone, bloody and disfigured on a tree for all of Jerusalem to see. The one so many thought to be God’s anointed, the deliverer, the outstretched arm of the coming righteous rule of God on the earth, dead and lifeless, asphyxiated on a cross, laid in a tomb like so many would-be messiahs.
And yet! Three days past, and the crucified and dead is alive—and not merely alive, but newly alive, the same yet different, restored and renewed yet utterly transformed, human, embodied, yet something more. The risen Jesus appears to his disciples and says, “Peace be with you! As the Father has sent me, I am sending you.” Yet they understandably ask, “Lord, are you at this time going to restore the kingdom to Israel?” This vindication of Israel’s Messiah as truly the bearer and messenger and harbinger of God’s reign on the earth, this apocalypse of Jesus Christ as Lord of all, surely it is the beginning of the end—surely God will establish his rule here, now, by this man. But Jesus replies: “It is not for you to know the times or dates the Father has set by his own authority. But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” God’s rule will come, is coming, is present even now in Jesus—but the final consummation is yet to come. For now, it is left for the apostles—literally, those sent—to live and proclaim before the world as witnesses of the good news that God’s reign is coming, but not only coming, has come, in the life, death, and resurrection of the Messiah, Jesus of Nazareth. And they are not alone in this, for the mission to the ends of the earth is grounded first and foremost in the power of the Holy Spirit; and God will pour out his Holy Spirit on his servants, both men and women, and thus a new people will be created, both Jew and Gentile, for the embodied taking of this mission, this witnessing, to the ends of the earth: the church.
The church, therefore, is the eschatological people of God. It is the new social body, created by God in Jesus’ death and resurrection, sent forth into all the earth to witness to the good news of God’s reign come in Jesus. It is the body of Christ, his visible presence in a suffering and violent world. It is the sign of the peaceable kingdom, whose life together points toward that day when all things will be made new, when the nations will no longer make war. It is the temple of the Holy Spirit, where the depth of God’s power and wisdom makes his home in the hearts and the actions and the worship of God’s people in the world. It is the radical dissolution of all “natural” divisions between male and female, Greek and Jew, slave and free, poor and rich, married and single, powerful and powerless—all are welcome at the table of God’s meal, prepared for the world. The church, in all its mistakes and all its hiccups, is the set apart people of God’s own choosing, sent into God’s beloved world with a mission to witness to the way of the reign of God. Just as God called and sent Abraham, just as God called and sent Israel, just as God called and sent Moses and David and Isaiah, called and sent Jesus the Messiah, called and sent Peter and Paul, promised and sent the Spirit in love—so God calls and sends the church of Christ in power and in grace for the sake of the world.
