'Many a tailor goes in rags, that maketh costly clothes for others; and many a cook scarcely licks his fingers, when he hath dressed for others the most costly dishes. Believe it, brethren, God never saved any man for being a preacher, not just because he was an able preacher; but because he was a justified, sanctified man, and consequently faithful in his Master's work. Take heed, therefore, to yourselves first, that you be that which you persuade them to be, and believe that which you persuade them to believe, and heartily entertain the Saviour whom you offer to them.'
Richard Baxter, The Reformed Pastor, p.54.
