Christians have a most important work to do. They are commissioned by God to watch for souls as they that must give an account. They are to reprove, rebuke, and exhort with all longsuffering. God said to the prophet Ezekiel, "So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me. When I say unto the wicked, O wicked man, thou shalt surely die; if thou dost not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood will I require at thine hand. Nevertheless, if thou warn the wicked of his way to turn from it; if he do not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul."

Kristne har en meget betydningsfuld gerning at udføre. Gud har befalet dem at våge efter sjæle som nogen, der skal aflægge regnskab. De skal tilrettevise, irettesætte og formane med al langmodighed. Gud sagde til profeten Ezekiel: "Men dig, menneskesøn, har jeg sat til vægter for Israels hus; hører du et ord af min mund, skal du advare dem fra mig. Når jeg siger til den gudløse: »Du skal visselig dø!« og du ikke taler for at advare ham mod hans vej, så skal den gudløse vel dø for sin misgerning, men hans blod vil jeg kræve af din hånd. Advarer du derimod den gudløse mod hans vej, for at han skal omvende sig fra den, og han ikke omvender sig, så skal han dø for sin misgerning, men du har reddet din sjæl."
