During the remarkable thirty-eight-year ministry of Charles Spurgeon in the city of London in the 1800s, no building seemed big enough to house all those who wanted to hear him preach. Spurgeon was noted as a passionate biblical expositor of the gospel who spoke the language of the common people and met them at the point of their deepest needs. Spurgeon was a seasoned veteran in meeting Satan at every corner and defeating Satan in the power of the gospel. But in keeping with his practical style, there was nothing abstract, ethereal, or mystical about Spurgeon's teaching. He directed his focus where he found Satan at work in the lives of people—enslaving them in sin, keeping them from the influence of the gospel, hindering their spiritual development, bringing discouragement, depression, and moral failure.
