The ecological imagination of Kim Nam-jo's poetry is based on the tradition of Christian thought. In the poetry of Kim, we can find sense of guilt and negative solitude based on the Christian thought. The faith of the poetic self turns the ‘relation-disconnection’ between the God and the human, the God and the nature, the nature and the human, to the ‘relation- connection’. The self has a Platonic orientation toward the heaven. And she shows the idea of Aristotelian organic nature. Both are based on the Christian theology. The organic nature is experienced as the Holy Mother. The concept of the Holy Mother is connected with the ancient mother goddess. But the Holy Mother belongs to the heaven unlike the mother goddess. The imagination of the Holy Mother resets the relationship between the nature and the human to the relationship between the mother and the children. Kim dialectically connects the science and the theology. Reinterpreting scientific cosmology from the perspective of faith, she shows the image of the planet earth as a community of lifes surrounded with the God's blessing. Kim's ecological imagination is not limited in the boundary of the earth, her ideal ecological community is the eco-topia of whole cosmos. Her ecological imagination shows interest in the relationship between the earth and the cosmos. Kim's imagination of Christian ecology has very important meanings in the history of Korean modern poetry, in the dimensions of post-war eco-poetics, the imagination of the Holy Mother and the dialectical imagination of the science and the eschatology.
