The article is basically a translation and commentary on the Gospel of John. It attempts to explore the contexts of Greek philosophy and Hebrew culture, in order to analyze the concept of love in this chapter. The following points are the focus of the discussion: First, love is to wash feet each other, to serve each other. Secondly, love is to obey God's will, rather than to insist one's good will, such as in Judas' insistence on his idealism. And thirdly, love is to follow Jesus, rather than to rely on one's judgment, such as Peter's courage to defend Jesus.
