In the global dimension, the issue regarding on life and ecosystem is the most significant topic in theology in these days. Essentially, the issue of life encompasses all dimensions of the biosphere and human life. The theme of WCC 10th Busan assembly, “God of Life, Lead us to Justice and Peace,” invites us to the mission Dei which includes all biospheres and human being. The theme implies that all biospheres including human being are the object of the redemptive action of the triune God because human life is deeply connected to all biospheres. Furthermore, the theme proves that God deconstructs the disorder of dehumanization, poverty, and oppression through the Holy Spirit. And the theme clearly confirms that God is the re?creator who brings justice and peace in the world. In this respect, the first purpose of this article is to articulate that all creatures should be included in the object of salvation and liberation in the mission Dei. The second purpose of this article is to articulate that the sphere of salvation and liberation should be extended into justice and peace. In the chapter II, I will describe the emphasis point of “‘Together towards Life: Ecumenical Affirmation on Mission and Evangelism in Changing Landscape” of CWME. In order to suggest the validity of the emphasis point, I will propose proleptic perspective as a theological foundation. Furthermore, I will introduce A Rocha`s movement to preserve all creatures as an example for the basis of the Old Testament and the mission of life. In the chapter III, I will articulate the relationship justice and peace in the sphere of the mission of life through examining “Economy of Life, Justice, and Peace for All: A Call to Action” and “An Ecumenical Call to Just Peace”. Futhermore, I will suggest the approach of a political philosophy about people who experience injustice without legal protection through Giorgio Agamben`s notion homo sacer.
