By 1909, it had spread to the Orange River Colony. In South Africa, as at Azusa Street, the movement was initially multi-racial, appealing to both Boers and blacks. It expanded rapidly among African farm workers in the Orange River Colony and Wakkerstroom, where Pentecostal beliefs in divine healing through prayer would have made it an attractive alternative to traditional or medical treatment. Lake made contact with the Wakkerstroom Zionists led by Pieter Louis Le Roux, and many Zionists joined the Apostolic Faith Mission. Their influence can be seen in the AFM's practice of baptism by triple immersion, once each in the name of the Father, and the Son, and the Holy Spirit. There was also interaction with other churches, such as the Plymouth Brethren and International Holiness movement, which often resulted in individuals or whole congregations joining the AFM. Most AFM converts, however, came from the Dutch Reformed churches.
