The following is from Luther’s “Preface to the Book of Romans,” to which John Wesley was listening at a meeting on Aldersgate Street when he found his heart “strangely warmed.”
The first duty of the preacher of the gospel is, through his revealing of the law and of sin, to rebuke and to turn into sin everything in life that does not have the Spirit and faith in Christ as its base. Thereby, he will lead people to a recognition of their miserable condition, and thus they will become humble and yearn for help.
