This study analyzes Korean-style fantasy narrative, interprets their ethical meaning, and approaches them with a Christian ethical perspective. First of all, this study examines the nature of narratives while attempting to understand Korean-style fantasy. To this end, this study selects “Along with God – the Two Worlds” as an example of Korean-style fantasy. It is the realization of justice and fairness based on causal retribution. In addition, this study overviews readers’ narratives through big-data analysis, which does not reveal much difference ethically between Christians and non-Christians, showing the lack of proper teaching of Christian ethics to church members. Thus, this study presents Christian ethical alternatives to approach these issues. This study proposes a Christian ethical practice of achieving justice through love beyond causal retribution, that is, to practice social ethics to create a community of peace, reconciliation, forgiveness, and hospitality. Also, the Korean church should shift from the afterlife-oriented perspective to the ethics of God’s kingdom. Because the kingdom of God has already begun with Jesus’ incarnation, and because the teaching of Jesus to live a life of loving his enemy means living a future-oriented (eschatological hope) life. Creating new narratives through these ethical lives will be the way to save the Korean church.
