Growing up in a Hindu temple in South India, Sadhu Chellappa mastered the Indian Scriptures. In the temples, he found practices and beliefs contrary to the scriptures. This led to his asking many questions to his teachers and masters. Not satisfied with answers he left the Hindu faith and became an atheist. After a series of failures he decided to commit suicide.

In a dramatic conversion, as he planned to jump from a train in the city of Madras, he heard a verse from the Bible being quoted by a preacher in a Christian meeting. "He who conceals his sins will not prosper, but he who confesses and forsakes them will receive pardon" (Proverbs 28:13). He immediately got down at the next station and walked to the meeting and he found the Lord Jesus Christ in his life.
