What sin is, is clearly shown by the holy Scriptures. The prophet Samuel said to Saul, when the latter had transgressed the commandment of the Lord: Disobedience is as the sin (mark, sin) of witchcraft. 1 Sam. 15:23. John says: All unrighteousness is sin. 1 John 5:17. James says: To him that knoweth to do good, and doeth it not, to him it is sin. Jas. 4:17. (Mark what sin is). Paul says: Whatsoever is not of faith is sin. Rom. 14:23.
From this and the like, my children, learn to know sin; as Paul says: By the law is the knowledge of sin. I had not known sin but by the law. The law causes sin to become exceeding sinful; for when it says: Thou shalt not covet, sin takes occasion, and works in us all manner of concupiscence. Rom. 3:20; 7:7,13. From this we also perceive, whereby sin became sin, namely, by the command and prohibition of God.
Every one who transgresses the things which God has commanded, commits sin, and it is also called sin, and punished as sin, fully and abundantly, in both Testaments. The tree of knowledge was not unclean for Adam, except through the commandment; his transgression was also called sin. As regards the punishment for this sin, read Gen. 3:14. The heathen daughters and wives were not unclean for the Jews, save through the commandment of God, who would not have it. Concerning the punishment, read Judg. 3; Num. 25. The sanctuary, or ark of God, which was certainly clean, was not unclean for any tribe, to touch or bear it, except through the commandment. Num. 4:17. The gods of the heathen were not unclean for Israel, save through the prohibition and proscription of God, also the commandment and the punishment. 1 Kings 15.
Behold, thus you can perceive whereby sin becomes sin, namely, through the commandment, and the transgressing of the commandment; for where no commandment is, there is no sin, for without the law sin was dead. Rom. 4:15; 7:8. For sin, or sinful action was in the world; but sin is not imputed when there is no law. Rom. 5:13.
Now, dear children, as soon as you know sin, learn to shun it as you shun fire; for if you approach sin, it will embrace you; but the stings and wounds thereof cannot be healed. Sir. 21:2,3.
Therefore, learn now to understand further, what proceeds from sin, and what are the wages of sin, for these are damnation and death. Rom. 6:23. It is enmity against God, because it is not subject to the law of God. Rom. 8:7. Hence hear further the terrible, relentless and awful punishment of God upon sin and sinners, which has ever taken place and will yet take place. Take heed, my dear children, I counsel you, as much as you value your souls, to this special, eternal punishment of sin and sinners. Thus says the Lord: I have long time holden my peace; I have been still, and refrained myself: now will I cry like a travailing woman; I will destroy and devour at once. Who among you, he says, will give ear to this? Who will hearken and hear for the time to come? The day of the Lord cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it. It is the day of the Lord’s vengeance, and the year of recompense for the controversy of Zion. And the streams thereof shall be turned into pitch, and the dust thereof into brimstone, and the land thereof shall become burning pitch. It shall not be quenched night nor day. Is. 42:14,23; 13:9; 34:8, etc.
This impending calamity, the punishment and righteous judgment of God, was announced and promised a very long time; for when Enoch, the seventh from Adam, was upon earth, he said: Behold, the Lord cometh with ten thousand of his saints, to execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him. Jude 14,15.
Mark, that God threatens and gives sufficient warning before, as he did to Assur: Woe be unto thee, Assur, thou that hidest the unrighteous in thee! O thou wicked people, remember what I did unto Sodom and Gomorrah; whose land lieth in clods of pitch and heaps of ashes; even so also will I do unto them that hear me not, saith the Almighty Lord. 2 Esd. 2:8,9.
The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity, and shall cast them into a furnace of fire. Matt. 13:41,42. Then shall the Lord say unto them on his left hand: “Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: for I was a hungered, and ye gave me no meat; I was thirsty, and ye gave me no drink.” Matt. 25:41,42. Behold, my dear children, thus shall it then go with those who do not now while it is time, regard this, being rich, filled and merry. For Christ says: Woe unto you that are rich, for ye have received your consolation. Woe unto you that are full! for ye shall hunger. Woe unto you that laugh now! for ye shall mourn and weep. Woe unto you, when all men shall speak well of you! Luke 6:24–26. When they lived, says Esdras, and received God’s benefits they did not regard it; they despised his counsel while they had yet liberty, and contemned repentance; therefore they must know it after death by torment. 2 Esd. 9:10–12. While we lived and committed iniquity, we considered not that we should suffer for it after death. 7:56. For the wages of sin is death. Rom. 6:23. But, after thy hardness and impenitent heart, thou treasurest up unto thyself wrath against the day of wrath, and revelation of the righteous judgment of God, who will render to every man according to his deeds; to them who by patient continuance in well-doing, seek for glory, and honor, and immortality, eternal life; but unto them that are contentious, and do not obey the truth, but obey unrighteousness; indignation and wrath, tribulation and anguish, upon every soul of man that doeth evil. Rom. 2:5–9.
Understand again, my dear children, into what great danger our evil flesh plunges us here, slaying the soul. The lust and works of the flesh cause eternal sorrow and loss of heaven. As Paul says: Walk in the Spirit, and ye shall not fulfill the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh; and these are contrary the one to the other; so that ye cannot do the things that ye would. Now the works of the flesh are these; adultery, fornication, uncleanness, lasciviousness, evil lusts—(read to the end of the seventeen points mentioned). And he says that they which do such things shall not inherit or possess the kingdom of God. Gal. 5:16; 1 Cor. 6:9. Then it shall not be possible for any one to be spared from the vengeance of God, whether he know God, or whether he know him not; if he has been disobedient to the Gospel, he must bear the severity of God. For Paul says: When the Lord Jesus shall be revealed from heaven with his mighty angels, in flaming fire, taking vengeance on them that know not God, and that obey not the Gospel of our Lord Jesus Christ; (mark) who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power; when he shall come to be glorified in his saints, and to be admired in all them that believe. 2 Thess. 1:7–10.
