What were some causes for disappointment in the healing revivals?

Some leaders felt that deliverance evangelism was declining because the evangelists began living on a coasting experience. The evangelists had left behind the power of God and had come to depend on gimmicks. Gordon Lindsay saw the decline in a lack of fasting and waiting, as well as in personal greed and positions and power. W. W. Raiford saw the era in endless internal competition and jealousy. While great crowds were brought under the tents and there was great commotion and excitement, there was also great greed and disappointment, ungodliness as well, and so the deliverance evangelists proved to be disappointing in the hope of reviving the Latter Rain Movement.
