If the Holy Spirit is the power of God, and God can work miracles, then they should expect miracles. They have a low tolerance for illness. In their insistence on this manifestation, Ford says, Pentecostals may come to hold the Holy Spirit as more important than Jesus himself. People who have trusted this phenomena to enable them to go to other countries as missionaries without language study have usually been disappointed. It is not necessarily supernatural.
Glossolalia is practiced by people in many cultures and religions.
Ford says this is blasphemous. Ford commented on the quest some Pentecostals have for the power of the Holy Spirit as evidenced in the signs and wonders. It is important to distinguish between the power of love and the love of power. There were people in Christ's day who would not believe unless they saw miracles, but he tried to teach them that the love of God has more power than any such signs. Even faith healing may be a problem, for people who think that their faith in a healer is what saves them.
