In our series of brief studies going through the ten commandments we now come to the seventh commandment, which says,
“Thou shalt not commit adultery.” (Exodus 20:14, KJV)
This commandment (like the rest of the ten commandments) is what I like to call an “umbrella category.” What I mean by that term is that this commandment represents a particular category of sins or transgressions, and so there are many different ways that a person can break it.
The seventh commandment, simply put, forbids sexual immorality of all kinds.
In the sermon on the mount (Matthew chapters 5-7) the Lord Jesus put it this way:
“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.” (Matthew 5:27–28, ESV)
Here Jesus teaches us the proper understanding of the seventh commandment. And in doing so He makes it clear that this commandment forbids not just sinful actions, but also sinful thoughts and desires as well! A person can be outwardly chaste, and yet inwardly still be guilty of adultery. And so it is not just sexually immoral actions that are to be avoided and repented of, but also sexually immoral words and thoughts as well.
This commandment against sexual immorality is worded in terms of the particular form of sexual sin that in some ways is the most heinous and serious version of it – adultery.
What makes adultery so serious a sin before God? Adultery, properly-speaking, is not just sexual immorality (as serious as that is), but is also theft (and so a transgression of the 8th commandment as well). Thomas Watson writes,
“It [adultery] is a thievish sin. It is the highest form of theft. The adulterer steals from his neighbor that which is more than his goods and estate; he steals away his wife from him, who is flesh of his flesh.” (The Ten Commandments, p.155)
It is also a violation of the marriage covenant, and so the breaking of one’s vows, and bearing false witness before God and man (and so also a violation of the 9th commandment). Clearly there is a great deal of overlap between the commandments, and in breaking one of them, we often tend to break others as well.
I’m tempted to say that this commandment is the most-neglected and most commonly broken of all of the ten commandments in our day, even among professing believers in Christ. (In all likelihood that dubious distinction probably belongs to either the 2nd or 4th commandments.)
Whatever the case, the seventh commandment is disregarded, redefined, and transgressed among many professing Christians to such a degree that there no longer seems to be much of a difference or distinction between the church and the unbelieving world around her.
This simply should not be so.
In 1 Thessalonians 4:3 Paul told the believers in Thessalonica, “For this is the will of God, your sanctification: that you abstain from sexual immorality.” He said that, not because sexual morality is the end-all, be-all of the Christian life, but because in a debauched culture, abstaining from sexual immorality is one of the primary distinguishing marks that set believers apart from the world around us.
That is as true in our day as it has ever been. Abstaining from sexual immorality is still very much the will of God for His redeemed people, and it is still our “sanctification,” something that sets us apart from the world.
May the Lord grant revival and repentance to many, starting with those of us who profess to know Christ, so that we might follow the will of God in these things. And may He grant repentance, faith, and forgiveness to many who have committed sexual immorality, that they might know peace with God, and begin to follow His will in these things.
