2. His business as a watchman is to give warning to sinners of their misery and danger by reason of sin. This is the word he must hear from God's mouth and speak to them. (1.) God has said, The wicked man shall surely die; he shall be miserable. Unless he repent, he shall be cut off from God and all comfort and hope in him, shall be cut off from all good. He shall fall and lie for ever under the wrath of God, which is the death of the soul, as his favour is its life. The righteous God has said it, and will never unsay it, nor can all the world gainsay it, that the wages of sin is death. Sin, when it is finished, brings forth death. The wrath of God is revealed from heaven, not only against wicked nations, speaking ruin to them as nations, but against wicked persons, speaking ruin to them in their personal capacity, their personal interests, which pass into the other world and last to eternity, as national interests do not. (2.) It is the will of God that the wicked man should be warned of this: Warn them from me. This intimates that there is a possibility of preventing it, else it were a jest to give warning of it; nay, and that God is desirous it should be prevented. Sinners are therefore warned of the wrath to come, that they may flee from it, Matt. iii. 7. (3.) It is the work of ministers to give him warning, to say to the wicked, It shall be ill with thee, Isa. iii. 11. God ways in general, The soul that sinneth it shall die. The minister's business is to apply this to particular persons, and to say, "O wicked man! thou shalt surely die, whoever thou art; if thou go on still in thy trespasses, they will inevitably be thy ruin. O adulterer! O robber! O drunkard! O swearer! O sabbath-breaker! thou shalt surely die." And he must say this, not in passion, to provoke the sinner, but in compassion, to warn the wicked from his way, warn him to turn from it, that he may live. This is to be done by the faithful preaching of the word in public, and by personal application to those whose sins are open.
