How Do Spiritual Awakenings Happen?

Pastor Thorleif Holm-Glad was walking through the empty sanctuary of Bethlehem Church in Oslo, Norway when the old caretaker of the church stopped him and soberly announced, "See these empty seats? This year there will be revival in this church!"  The pastor was startled to say the least.  Yes, he knew the church had empty seats and plenty of them.  No, not during the week when people were working but during services when the empty seats should have been filled. He also knew the caretaker was a good man, not given to exaggeration.
