The concept of globalization has emerged as a powerful paradigmatic concept in explaining many far-reaching economic, social, and cultural transformations in many parts of the world. Globalization can be defined as all the multi-dimensional process by which peoples of the world are incorporated into a global society. The drives of globalization are the tools of modern technology and the free market economy. The purpose of this paper is to understand globalization as a modern context for mission and how it has influenced the Korean church. This paper argues that globalization is not only opportunities for Christian mission but also obstacles against it. This paper discusses some benefits and obstacles to mission. For example, in an age of globalization more and more people can have an opportunity to hear the Gospel message, however, it makes more difficult for them to be disciples. Globalization encourages the context to foster the privatization of Christian faith. The paper suggests some future tasks for the Korean church in an age of globalization: the development of partnership, faith community, worldwide and communal sense of responsibility, and Christian civil society movements. It is hoped that the Korean church will contribute to the globalization of Christian gospel in the future, by embracing the global vision, one Kingdom of God under Jesus Christ.
