Born in the northeast of Scotland, John Ross arrived in Manchuria in 1872 and spent 40 years of his life there. He left behind an amazing legacy of culturally sensitive evangelism, established presbyterian churches, innovative missionary principles, valuable publications, and a rich vein of translations, including the first version of the New Testament in Korean. John S. Ross's riveting biography tracks not only his life, but also the social, political and spiritual influences which shaped his life and work. God is still using John Ross's labours to grow his Kingdom in South and North Korea today.
