I exhort you and beseech you in the bowels of Christ, faint not, weary not. There is a great necessity of heaven; you must have it. All other things, as houses, lands, children, husband, friends, country, credit, health, wealth, honour, may be let go; but heaven is your one thing necessary, the good part that shall not be taken from you. See that you buy the field where the pearl is. Sell all, and make a purchase of salvation. Think it not easy; for it is a steep ascent to eternal glory; many are lying dead by the way, that were slain with security.
