Many have warned others that they come not to that place of torment, while yet they hastened to it themselves: many a preacher is now in hell, who hath a hundred times called upon his hearers to use the utmost care and diligence to escape it. Can any reasonable man imagine that God should save men for offering salvation to others, while they refuse it themselves; and for telling others those truths which they themselves neglect and abuse? 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, nor 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 ourselves first, that you be that which you persuade your hearers to be, and believe that which you persuade them to believe, and heartily entertain that Savior whom you offer to them. He that bade you love your neighbors as yourselves, did imply that you should love yourselves, and not hate and destroy yourselves and them.
-Richard Baxter (1615-1691)
