CHAPTER X.

THE SIXTH COMMANDMENT.
PURITY. MARRIAGE.

Thou shalt not commit adultery.

What is meant by this Commandment?

We should so fear and love God as to be chaste and pure in our words and deeds, each one also loving and honoring his wife or her husband.


This commandment is meant to preserve our personal purity, and to guard the holy estate of marriage. It forbids adultery and all impurity. It commands chastity and purity in thought, word, and deed.

I. PURITY.

We should be CHASTE AND PURE

In Heart. We should keep our heart free from impure thoughts and desires. [Matt. 5:8+, Prov. 4:23+, Ps. 51:10] God judges us by the state of our heart. [I Sam. 16:7] Unchaste thoughts must not be delighted in nor harbored, but subdued and stamped out. They poison the soul. They are themselves a transgression of this commandment, [Matt. 5:28+] and they lead to further transgressions of it by word and deed.

IN WORDS. We must avoid immodest conversation, unchaste words, vile stories, and shameless jests. [Eph. 5:3-4, Eph. 4:29+] Such things are not smart, as many think, but vile and despicable. We should never take part in nor listen to a conversation which we would be ashamed to have overheard by persons whom we respect.

IN DEEDS. We should carefully avoid every act which would bring the blush of shame to our cheeks if it were known to our parents or others whose opinion we cherish. Our bodies are to be God's temple, [I Cor. 6:19, 20+] and they dare not be given over to sin and impurity. [Rom. 6:13] We should remember that God sees even in secret, and knows all our actions. [Ps. 139:1-12]

Impurity of heart and life will not go unpunished. [I Cor. 3:16, 17+, Gal. 5:19-21+] It is often followed by the most dreadful consequences: a ruined body, an enfeebled mind, a poisoned soul, a tortured conscience, public shame, dreadful disease and an untimely death.

To Keep ourselves Pure we should watch and pray, [Matt. 26:41+] avoid idleness, evil company, bad books and papers, indecent songs and pictures, immoral plays, intemperance in eating and drinking, and all that would incite to impurity. We should keep our minds occupied with good thoughts and desires, so that we have no room for evil ones. [Rom. 13:14]

II. MARRIAGE.

Marriage is the union of one man and one woman for life in the bonds of love and faithfulness.

A Holy Estate. Marriage was instituted by God in Eden [Gen. 2:13] and was sanctioned by Christ, who performed His first miracle at a wedding. [John 2:1-11] It is a holy estate. Celibacy is not a holier estate than marriage, as the Roman Catholic Church maintains. [I Tim. 4:1-3]

Indissoluble. The marriage tie is binding until one of the married persons dies. [Matt. 19:6+] Except by death, the marriage relation cannot be broken or dissolved without sin against this sixth commandment. [Matt. 5:32+, Matt 19:9] If one party to the marriage is guilty of adultery, the innocent party may obtain a divorce. No other divorces are allowed by Christ.

An Important Step. Marriage is a most important step in life. It must not be entered into hastily or thoughtlessly. If a mistake is made in the choice of a partner for life, the mistake can never be remedied. Those who contemplate such a step should pray for God's guidance. Marriage should not be entered upon for money, social advantages, and the like, but for love. Parents should be consulted. While marriage by a civil magistrate is valid, Christians should seek God's blessing upon their union and be married by His ordained servant. The laws of the State must be carefully obeyed. Marriage between near relatives is forbidden by God's Word. [Lev. 18] Those who are married should, if possible, be of the same faith. Marriages between Protestants and Roman Catholics are seldom happy.

Duty of Husband [Eph. 5:25+, Col. 3:19] and Wife. [Eph. 5:22+, Col. 3:18] EACH SHOULD LOVE AND HONOR HIS WIFE OR HER HUSBAND. The man is the head of the family, but he must not be a tyrant. The wife is not his slave, but his dearest companion. They are no longer two but one, with a common love, a common life, a common property, common children, common hopes and aspirations, and a common Saviour. [I Pet. 3:7, I Pet. 3:1] They should be patient with one another's faults, just to one another's virtues, and should unselfishly seek one another's happiness. They should live together in mutual love and faithfulness till separated by death. Only when husband and wife continue to love and honor one another can they be happy. The breaking of the marriage covenant is followed by shame and misery.
