The Seventh Commandment is a simple, unqualified, irrevocable, negative: “thou shalt not.” No argument is used, no reason is given, because none is required. This prohibition is designed to guard the sanctity of the home, for strictly speaking “adultery” is a crime which none but a married person can commit.
God instituted the ordinance of marriage “to avoid fornication, let every man have his own wife, and let every woman have her own husband” (1 Corinthians 7:2). The intimacy of the marital relationship is to be guarded fiercely, so husbands are called to be a “one-woman man.”
To live effectively, we men need to cultivate a habitual sense of God’s presence, knowing “the eyes of the Lord are in every place, beholding the evil and the good” (Proverbs 15:3). We must be like Job, who said, ““I made a covenant with my eyes not to look lustfully at a young woman” (Job 31:1). Finally, we must focus our energies and not be idle since idleness often proves fatal.
