Sadhu Sundar Singh (1889-1929) was a Christocentric Indian Christian Mystic, known for his efforts to Indianize Christianity and whose thoughts on Christ, Bible, Spirituality, Christianity etc, are very original. Born in Sikh religion, by the age of sixteen he read Bhagavadgita and memorised Granth, Koran and several Upanishads. He hated Christianity so much, that he tore up and burnt the bible at this teen age. But next year, in a powerful vision he saw Jesus and was converted to Christianity. At the age of Seventeen, he set out on his journey as a new Christian, penniless, except with a New Testament copy, wearing a saffron turban and the saffron robe of a sadhu, as an ascetic devoted to spiritual practice, to preach the Gospel and about Jesus. Due to the Sadhu's uncanny physical resemblance to the Incarnate Jesus, similarities to the life and ministry of Apostle Paul, he was considered as a Biblical gure coming alive. He travelled extensively in India and around 24 countries in his missionary work. His thoughts on Prayer, Visions, Bible, and Heaven on Earth etc were so strong and original, that it even surprised most of the western theologists. His entire theology is based on his personal and spiritual experiences (Anubhava) with Lord Jesus. His thoughts about the primacy of Prayer in a Christian's life are compa red with that of other great European Christian mystics like St. Augustine, St Francis of Assisi, and St. Thomas a Kempis. Many of his theological thoughts are similar to that of Luther, even though he never met him nor read about him, but he also had some differences too. In his various severe sufferings that he faced in his efforts to preach the Gospel, even when he was persecuted, left to dead, imprisoned in Ilom, dumped in a dark well in Rasar, among skeletons and bones, he said Christ's presence has turned his prison or hell into a heaven of blessing. In him Christianity and Hinduism meet, and the Christian is like a ower which blossoms on an Indian stem. He says non-Christians, who did not get an opportunity or left an opportunity to accept Jesus, will get another opportunity afterlife to have their false and partial views of truth corrected. Even though he says all other religions are inadequate and only through Jesus one can get salvation, in his fullment approach, he says there is dim measure of “light of the truth” among the followers of different religions and provides for “continuity” in fullment and that they will eventually get full knowledge of true God, the “True Reality”. Sundar Singh is thoroughly convinced, that Christianity can enter Indian hearts and souls if offered in Indian form. He had done more than any man in the rst half of the twentieth century to establish that "Jesus belongs to India” and Christianity is not foreign.
