One of the missionaries working with William Carey was a physician named John Thomas. It was Thomas who won the first Hindu in India to Christ, after years of fruitless labors.
A man, named Krishna Pal, fell and broke his arm, and Dr. Thomas was sent to set it. When he was finished, he shared the gospel with the injured man. Krishna was deeply affected and was even moved to tears. He asked for more instruction. Before long, he openly renounced his idolatry, professing his faith in Jesus Christ as his Saviour. Then as a testimony to his conversion he shared the gospel with his wife and daughter, and all three offered themselves as candidates for baptism. Immediately the wrath of the neighborhood fell on the small family, and the two ladies decided against making a public testimony in baptism at that time, but Krishna was adamant. On this day (December 28) in 1800 before a huge crowd of Mohammedans and Hindus, and with the Indian Governor present, William Carey, Krishna and Carey’s son, Felix, walked into the Ganges River. The Missionary explained that it was not the water of the “sacred river” that washed away sin; it was the blood of Jesus Christ. It was a wonderful service touching many hearts and even bringing tears to the Governor’s eyes. Thus it was on this day in 1800, the first Hindu in India made a public profession of his faith. For the next twenty years Krishna Pal preached the message of Christ which had brought him to salvation.
