“ Lastly, Spurgeon reminds us that piety and devotion to Christ are not preferable alternatives to controversy, but rather that they should - when circumstances demand it - lead to the latter. He was careful to maintain that order. The minister who makes controversy his starting point will soon have a blighted ministry and spirituality will wither away. But controversy which is entered into out of love for God and reverence for His Name, will wrap a man's spirit in peace and joy even when he is fighting in the thickest of battle. The piety which Spurgeon admired was not that of a cloistered pacifism but the spirit of men like William Tyndale and Samuel Rutherford who, while contending for Christ, could rise heavenwards, jeopardizing 'their lives unto the death in the high places of the field'. At the height of his controversies Spurgeon preached some of the most fragrant of all his sermons. ”
