The study focuses developing an effective mission strategy in a Social Network Service culture to reach the net generation in Korea. It asks these important questions: “What are the barrier for the Korean churches in evangelism to the net generation?” “How can Korean churches change their SNS culture in mission for the unchurched net generation?” In order to answer these questions, data was collected through questionnaires and interviews with members of the net generation in Korea. Both the characteristics of the net generation, and those of the emerging SNS culture in Korea, were analyzed.The effective strategies of Korea church mission was an important issues in this study of how best to reach for Christ the net generation in SNS culture. I think that experience of mission in the Korean context led N-generation to the strategy that the Korean churches need a mission approach using SNS culture. This evangelism is a challenge for Korean churches seeking to reach the net generation. Korean churches need to be develop the mission strategies using SNS appropriate for the Internet culture of the net generation. Such SNS must be part of an effective mission toward the net generation who embrace a SNS culture.

This paper is to study historical characteristics of social service mission in Korea church before the 1945 liberation of Korea. The classification of an era for historical analysis about social welfare in Korea church is not only necessary, but also is dangerous. Because it could be depended on subjective classification of the researcher, simplified complicated historical processes, and there would be a possibility to classify it individually or selectively. Nevertheless, a missiotheological reflection about christianity society service in the Korea mission history will be meaningful to many people who study social service mission according to the classification of an era and important to Korea church which is in stagnation. In this context, the summingup to social service mission of Korea church before the 1945 liberation of Korea according to period features is necessary. There are two kinds of mission service characteristics in the protestant. One of these is Luther, Calvin and Knox as an ‘ecclesiastical’ type, and the other is sure salvation by individual experience of faith as a ‘nonecclesiastical’ type. Mission movement after Pietism mainly took the 'nonecclesiastical' type. The United States of America which preached the gospel to Korea also was offsprings of the ‘nonecclesiastical’ type. The faith of these people, as a type of pious Puritan, thought a concept of church is the same as an ark separated from the world. It shows at the constitutional law of the separation of religion and politics and the guideline of mission agency. Despite their spiritual salvation separated from the world, nonpolitical actions, and irrational and dualistic faith as what is called an ‘evangelist,’ these people began education and medical works as a starting point of mission at the beginning of Korea mission. These were based on the considerate help and charitable service by each missionary. This type of faith made emotional bond with Koreans in unhappiness as a method for propagating the gospel even though there was not an attempt grasping the underlying and structural problems which were causing miserable lives and political suppression to the pioneer missionaries. So, the local section was set up in ‘Christian Council’ in 1925 and the rural section was set up in 1930, but these were only recognized as ‘something for mission works.’ For example, the local section of ‘Christian Council’ in 1930 was limited only for the dormitory foundation, missionary sending, sewage factory demolition, temperance movement and combined execution of help works. This kind of early mission, which was an unstructural service has the same basis with pious ‘Mitleid’ to the lost souls. Pietism against protestant’s legitimism in the 17th century and illuminism in the 18th century was an important movement that awakened stagnated mission work newly, but focusing on an individual’s complacency and conversion it became the important motivation of mission and the important goal of mission only to save each person from corrupted world. Therefore, the mission of unstructural service has some limitations that restrict missionary works only as a province of converted spirit, given Missio Dei erecting the sovereignty of Jesus Christ and expending the kingdom of God in this world. It was from 1920 that Korea church started to recognize the basic cause of social problems systematically. And also this is originated from the development of international missiotheology. As the first World Missionary Conference held in Edinburgh in 1910 predicted the world evangelization hopefully, it was based on mission for a human being’s spirit salvation. Consequently, it did not develop the christianity's influence beyond individual spirit salvation. But after Edinburgh conference the world’s history was changing by contraries because of World War. So the World Missionary Conference after 1910 was not held. In Jerusalem conference in 1928 the recognition about the social responsibility of gospel, secularism and other religions was on the rise strongly. Thus, Korea church in the 1920s was interested in social welfare mission according to the stream of world missionary and the social change of Korea(Chosun). Since this was the creed copy of churches of the United States of America and Japan, this social welfare mission had a problem not to include independency and a demand of the times. Many social service movements such as roll back of tuberculosis, medical work, settlement work and moderation movement, and service for women and children’s welfare, therefore, showed the limitation. During the Japanese colonial period Korea church tried to find a clue of national problem solution from a rural community movement because it was based on a type of national church against Japan. The rural community movement also developed actively for about 10 years from the 1920s to the mid of 1930s. However, it should be stopped due to the oppression in and out of church from 1938, for it should choose either religious martyrdom or a conversion to rural community movement. Korea church have experienced a special period in which it practiced society service jointly with Korean people who were in poverty, diseases, oppression and discrimination under the Japanese colonial rule. Nevertheless, Korea church separated from the society due to the limitation of its conservative theology that could not catch fundamental social problems structurally and the faith that salvation is restricted within the individual spirit. This is why Korea church is experiencing its stagnation since the 1990s.
