As sexual sins continue to increase in our society, we need to be ready with scriptural answers as to why these activities are indeed sin. A few weeks ago we looked at the sin of fornication. The Bible clearly condemns such sexual activity. The focus of this article will be upon adultery as a sin. Many today simply do not understand what adultery is. There have been others who have been mislead by false teachers as to the definition of adultery. Let’s look at what the Bible has to say about it.
The sin of adultery is first discussed in the ten commandments. Exodus 20:14 says, “Thou shalt not commit adultery.” The commandment assumes that everyone knows what adultery means, but in looking through the scriptures, we see it defined in several scriptures. Leviticus 20:10 states the following: “And the man that committeth adultery with another man’s wife, even he that committeth adultery with his neighbour’s wife, the adulterer and the adulteress shall surely be put to death.” From this passage we learn that adultery is something that a man and a woman do together. It is something that is done with someone else’s spouse. Jeremiah 3:8 speaks of adultery in the same context as one who is a harlot. A harlot is a prostitute, someone who commits fornication for money. Jeremiah 29:23 confirms that adultery is something done with another’s spouse: “Because they have committed villany in Israel, and have committed adultery with their neighbours’ wives, and have spoken lying words in my name, which I have not commanded them; even I know, and am a witness, saith the LORD.” Ezekiel 16:32 perhaps gives us the clearest definition, “But as a wife that committeth adultery, which taketh strangers instead of her husband!” So we conclude from these scriptures that adultery is fornication with someone else’s spouse. This is the basic biblical definition of adultery. Other passages that place adultery within the realm of sexual sins are: Proverbs 6:26; Hosea 4:13; 1 Corinthians 6:9; and Hebrews 13:4.
The Bible clearly teaches that adultery is a sin. 1 Corinthians 6:9 states, “Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind
