Martin Luther - "The first duty of the gospel preacher is to declare God's law and show the nature of sin, because it will act as a schoolmaster and bring him to everlasting life which is in Jesus Christ."
John Wesley - "Before I preach love, mercy and grace, I must preach sin, law and judgement."
Wesley, later advised a friend to "Preach 90 percent law and 10 percent grace."
Charles Spurgeon - "They will never accept grace, until they tremble before a just and holy law."
Charles Finney - "Evermore the law must prepare the way for the gospel; to overlook this in instructing souls is almost certain to result in false hope, the introduction of a false standard of Christian experience, and to fill the Church with false converts."
John Wycliffe - "The highest service to which a man may attain on earth is to preach the law of God."
D.L. Moody - "God, being a perfect God, had to give a perfect law, and the law was given not to save men, but to measure them."
