Highlander Duncan Campbell (1898-1972) was used of God in powerful revival in the Hebrides of Scotland. At one village the Christians opposed Campbell's message of entire sanctification and the evangelist had little success. He and others were in prayer one night but had no release until a young man dared to pray an audacious prayer. Listen to it for yourself, in Campbell's thick Scottish brogue. Click on the sermon, "Then the Fire of the Lord Fell" and forward it to 58:55 to hear the event and the results.
Was the young man presumptuous? Campbell didn't think so and neither do I. I believe the man—moved by the Holy Spirit's direction—prayed the prayer of humble faith, not arrogant presumption.
