John Wimber was an American pastor and musician, best known as a co-founder of the Vineyard Movement, a Christian denomination that emphasizes contemporary worship and healing. Born on February 25, 1934, he initially pursued a career in music before turning to ministry in the 1970s. Wimber's teachings focused on the importance of experiencing the Holy Spirit and the practice of spiritual gifts. Wimber played a significant role in the charismatic movement, which sought to renew interest in the gifts of the Spirit within mainstream Christianity. He authored several books and was influential in promoting the idea of "power evangelism," which emphasizes the demonstration of God's power through healing and miracles as a means of sharing the Christian faith.
