It’s Two-fer Tuesday, so I’ll give you a couple different quotes:
A good preacher should have these properties and virtues; first, to teach systematically; secondly, he should have a ready wit; thirdly, he should be eloquent; fourthly, he should have a good voice; fifthly, a good memory; sixthly, he should know where to make an end; seventhly, he should be sure of his doctrine; eighthly, he should venture and engage body and blood, wealth and honour, in the word; ninthly, he should suffer himself to be mocked and jeered of every one.
He should not be silent or mumble but should testify without being frightened or bashful. He should speak out candidly without regarding or sparing anyone, let it strike whomever or whatever it will. It is a great hindrance to a preacher if he looks around and worries about what people like or do not like to hear, or what might make him unpopular or bring harm or danger upon him. As he stands high on a mountain in a public place and looks around freely, so he should also speak freely and fear no one, though he sees many kinds of people and faces. He should not hold a leaf in front of his mouth.
