"The Reformation was a revival of true gospel preaching, and such gospel preaching always comes down to the point of decision. Good preaching is aimed at the will; all good preaching aims at conversion. If the people are not converted, they need to be. If they are, then a message aiming at true conversion will encourage them, not beat them up. As Luther put it, we are called to a lifetime of repentance.
Good preaching reminds every Christian soul that we live before the God who sees and knows the heart, and who will sift those hearts in the great day of judgment. The problem arises when the need for true conversion is moved from the declaration of the gospel to the membership interview. The former declares the truth with the understanding that only God can see the heart. The latter, in the name of God seeing the heart, pretends that the minister and elders can see the heart."
