Two sons of Rev. Yang-won Shon were killed because they refused to abandon Jesus and to agree with leftwing students. Afterwards, Rev. Yang-won Shon forgave the one who killed his sons and adopted him as his son. And he showed him the love of Jesus Christ, taking care of lepers. He was called the 'The Atomic Bomb of Love.' In this manner, if we become a single rotten piece of grain or we can bear great fruit of the gospel. When we become the light and salt of the world, sacrifice ourselves, and serve others, we can show the love of Jesus Christ and lead many people to the path of salvation.
"Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit." (John 12:24)
