If you look back across the history of the Christian Church, you immediately find that the story of the Church has not been a straight line, a level record of achievement. The history of the Church has been a history of ups and downs. It is there to be seen on the very surface. When you read the history of the past you find that there have been periods in the history of the Church when she has been full of life, and vigour, and power. The statistics prove that people crowded to the house of God, whole numbers of people who were anxious and eager to belong to the Christian Church. Then the Church was filled with life, and she had great power; the Gospel was preached with authority, large numbers of people were converted regularly, day by day, and week by week. Christian people delighted in prayer. You did not have to whip them up to prayer meetings, you could not keep them away. They did not want to go home, they would stay all night praying. The whole Church was alive and full of power, and of vigour, and of might. And men and women were able to tell of rich experiences of the grace of God, visitations of his Spirit, a knowledge of the love of God that thrilled them, and moved them, and made them feel that it was more precious than the whole world. And, as a consequence of all that, the whole life of the country was affected and changed.
