John G. Lake (1870-1935) was an American revivalist and Pentecostal leader who was known for his healing ministry and revival efforts. Born in Canada, Lake emigrated to the United States and became a successful businessman. In the early 20th century, he became a devout Christian and was drawn to the teachings of the Pentecostal movement, which emphasized the experience of speaking in tongues and the gifts of the Holy Spirit.
Lake became a prominent voice in the Pentecostal movement and was known for his healing ministry, which drew thousands of people to him. He traveled extensively, preaching and leading revival meetings, and became a sought-after speaker and writer. Lake also founded several institutions, including the Apostolic Faith Mission, a mission organization that sent missionaries to other countries. Despite his success, Lake remained humble and dedicated to his faith, and he continued to preach and teach until his death in 1935. Today, Lake is remembered as a powerful voice in the early Pentecostal movement and as a pioneer of the healing revival.
