In an epilogue, Hermisson explores contemporary implications for the Christian community, calling for active engagement with the world while maintaining hope in God. Hermisson also finds Zion profiled as queen, whose elevation necessitates Babylon's defeat. As the prophet represents the model for Israel, so Israel is the model for the world. Regarding the second pair of themes, YHWH's creative word is the central theological motif of Deutero-Isaiah's pronouncement. Creation is the theological horizon that encompasses God's saving activity.
Salvation is new creation.
Hermisson argues that the Zion texts concentrated in the second half of the book and the Babylon poem of chapter 47 are authentic to Deutero-Isaiah, as well as the first three servant songs. The ipsissima verba of the prophet, however, are unattainable. The prophet's disputation with his people is from the outset theological. He finds that the prophet's success, amid resistance, is accomplished only through YHWH's success. The Servant is situated between Israel as passive, disloyal witness and Israel as an active, ideal witness to the world.
