" In a sense one should not go to books for ideas; the business of books is to make one think. We are not gramophone records, we are to think originally. What we preach is to be the result of our own thought. We do not merely transmit ideas. The preacher is not meant to be a mere channel through which water flows; he is to be more like a well. So the function of reading is to stimulate us in general, to stimulate us to think, to think for ourselves. Take all you read and masticate it thoroughly. Do not just repeat it as you have received it; deliver it in your own way, let it emerge as a part of yourself, with your stamp upon it. "

― D. Martyn Lloyd-Jones , Preaching and Preachers
