In 1946-1947 a great movement of fasting and prayer was spawned, first in America and then the rest of the world. Franklin Hall’s book ‘Atomic Power with God through Fasting and Prayer’ was the spark that ignited the hearts of thousands to go on extended fasts, to seek God for revival and the restoration of spiritual gifts to the church.

Many went on 40-day fasts. In 1947-1952 the great Healing Revival broke out through the ministries of William Branham, Oral Roberts, T. L. Osborn and a host of others who began to experience gifts of the Holy Spirit. They began to see extraordinary miracles in their ministries and thousands were converted and healed. Most of these itinerant evangelists followed hall’s practice of fasting.

In 1948 the “Latter Rain” outpouring visited North Battleford, Canada, and swept into the United States.  The leaders all agreed that it was after reading ‘Atomic Power’ that they entered a season of the “grace of fasting” which, after three months, resulted in a powerful outpouring of the spirit restoring spiritual gifts and ministries to the church. It also led them into employing the ‘laying on of hands’ for healing and for imparting the gift of the Holy Spirit.

The truth and practice of fasting with prayer was a major catalyst in this revival.
