On January 1, 1901, after a watch night service, the students prayed for and received the baptism with the Holy Ghost with the evidence of speaking in tongues. Parham received this same experience sometime later and began preaching it in all his services. Parham believed this was xenoglossia and that missionaries would no longer need to study foreign languages. After 1901, Parham closed his Topeka school and began a four-year revival tour throughout Kansas and Missouri.
Walter V. Grant Sr. 1913-1983 was a Pentecostal preacher who was filled with spiritual wisdom and homespun humor. Many were healed instantly as Bro. Grant requested them to do something out of the ordinary. A man of spiritual discipline, Grant lived in the Spirit. He was Gordon Lindsay's editor for the Voice of Healing magazine, he pastored Jack Coe's church Dallas Revival Center and later pastored Soul's Harbor Church. Grant is a legend in healing evangelism.
