In this article, the author examines the meaning of Galatians 2:20. And in that sense, we looked at the life of pastor Yangwon Son. Galatians 2:20 is widely discussed within the church, yet receives minimal attention in systematic theology. So Friderike Nüssel, a systematic theologian at the University of Heidelberg, presents an overview of the passage. According to her interpretation, Galatians 2:20 can be understood to mean "being in faith" and "living in service of Jesus Christ". Being in faith refers to a new creation in Jesus Christ. This new existence means freedom from the law, union with Christ, and living for the sake of Jesus Christ's other. To live in the service of Jesus Christ is to live for the glory and will of Jesus Christ, not your own. The life in the service of Jesus Christ is a life of selflessness for the sake of others because we follow Jesus Christ. Being a new creation, freedom from sin and the legalism, does not mean living a life of disconnected faith. Rather, it is a life that seeks to resemble Jesus Christ while being sensitive to even the smallest sin within. Rather, it is a life that strives to emulate Jesus Christ while remaining aware of even the slightest sin. Pastor Yangwon Son led such a life, determined to combat sin with unwavering fortitude. He was a great man who devoted his life to Jesus Christ and the congregation he served. The meaning of Galatians 2:20 emphasizes balancing faith and outward life, contending against sin, and living for the gospel and the kingdom of God. Pastor Yangwon Son lived such a life, who faced the Japanese with a ready-to-die spirit, endured torture, adopted his sons' killers, defended the church and leper congregation, and ultimately died a martyr. The recent Korean church is in crisis because it no longer pursues this type of pastor. The separation of faith and life, Christian selfishness that seeks only one's own blessing and security instead of living for Jesus Christ, and the church's pursuit of external growth have diminished the important values that Christianity should pursue. Yangwon Son was aware of the slightest wrongdoing within, and he stressed the importance of prayer to live according to the truth rather than indulging in prayers that serve only one's selfish desires. And through the pastor's genuine affection for the leper, his forgiveness towards his enemies who had killed his sons and his decision to adopt them as foster sons, he emerged as a symbol of extraordinary love, embodying the love of Jesus Christ. And instead of fleeing to protect the leper church members, he was martyred by the Communists. Christians cannot live like Yangwon Son, but if they confess Galatians 2:20 correctly, they will strive for this kind of life. The restoration of the Korean church will only commence with this kind of faith.
