A man that preaches an immortal crown, should not seek much after transitory vanity. And he that preaches the contempt of riches should himself contemn them and show it by his life. And he that preaches self-denial and mortification should practice these virtues in the eyes of them to whom he preaches, if he would have his doctrine believed. All Christians are sanctified; and, therefore, themselves, and all that they have, are consecrated “to the Master’s use.” But ministers are doubly sanctified: they are devoted to God, both as Christians and as ministers; and, therefore, they are doubly obligated to honor Him with all they have.
Richard Baxter
