In this week’s installment from Off the Record with Martin Luther, Luther explains how a preacher is like a carpenter:

234. A preacher is like a carpenter; his tools are God’s Word. Because the audience, upon whom he is to work, is diversified, he should not continuously teach in the same tone, rather, in respect of the differences in his congregation, comfort for a while, frighten, scold, offer reconciliation, and so on (p. 209)
