Take heed of yourselves

From The Reformed Pastor by Richard Baxter:

See that the work of saving grace be thoroughly wrought in your own souls. Take heed to yourselves, lest you be void of that saving grace of God which you offer to others, and be strangers to the effectual working of that gospel which you preach; and lest, while you proclaim to the world the necessity of a Savior, your own hearts should neglect him, and you should miss of an interest in him and his saving benefits. Take heed to yourselves, lest you perish, while you call upon others to take heed of perishing; and lest you famish yourselves while you prepare food for them.
