Machen on the Second Use of the Law

J. Gresham Machen on why we need better preaching of the Law (note that neither those who wonder What Jesus Would Do, call themselves Promise Keepers, or seek to lead Purpose Driven Lives have truly heard the Law preached as Machan would have it preached):

A new and more powerful proclamation of law is perhaps the most pressing need of the hour; men would have little difficulty with the gospel if they had only learned the lesson of the law. As it is, they are turning aside from the Christian pathway; they are turning to the village of Morality, and to the house of Mr. Legality, who is reported to be very skillful in relieving men of their burdens... 'Making Christ Master' in the life, putting into practice 'the principles of Christ' by one's own efforts-these are merely new ways of earning salvation by one's obedience to God's commands.
