I, Monster challenges common assumptions about the Gospel by reframing Sin and Death not as abstract moral failures or metaphors for bad behavior, but as active powers that shape human existence and distort creation. Drawing on the New Testament and early Christian theology, the book argues that the Gospel is not primarily about escaping guilt or attaining heaven, but about God's decisive confrontation with these powers through the life, death, and resurrection of Jesus.Engaging key biblical texts and theological traditions, I, Monster explores questions of human nature, embodiment, and salvation, offering a theological anthropology that understands humanity as contested ground within a larger cosmic struggle. By situating Jesus' mission within this framework, the book invites readers to reconsider how the Gospel addresses the deepest problems facing humanity and what it means to be fully human in light of God's redemptive action.Written for thoughtful readers, students, and those interested in serious theological reflection, I, Monster presents a rigorous yet accessible reexamination of the Gospel story and its implications for Christian theology today.
