In Korea, while society is becoming an aging one, various problems are being brought about, such as disease, poverty, alienation, and so on. So long life is not a blessing any more. Rather it becomes a cause of suffering to a lot of the aged. In this sense, aging is not received positively. Among various problems in aging society, this thesis dealt with how to overcome the aged's alienation which was brought about by the loss of their roles in society and even in the church. And this thesis conducted a project to help them to recover their self confidence. This project conducted by recruiting 20 people among the aged who participated in the seminar for the aged, "Beautiful Life." They were composed of 10 men and 10 women. The project was planed of the service education for four weeks and the service practice for two weeks. And to see how they changed between before and after the project, this thesis surveyed them by several questions. Analyzing the survey, we could find that service was a good way to overcome the aged's alienation by the loss of their roles. Therefore, we can conclude that to positively encourage the aged to participate in service helps them to experience God's love and grace for them, and thus it helps them to overcome their alienation.
