What does Proverbs 6:32 mean?

Scripture doesn't merely indicate that adultery is a sin (Exodus 20:14), or that it risks terrible consequences (Proverbs 6:27–31). The Bible also points out that adultery is foolish. In the context of Proverbs, "foolish" means something lacking in good sense, morality, wisdom, and so forth. In modern English, we might say "it's a stupid thing to do." Biblical foolishness, however, doesn't involve intelligence. Some very smart people are nevertheless extremely foolish; many are caught in adultery. In the grip of lust and temptation, those committing adultery often don't consider how destructive it is. Or, they know the risks but think pleasure is worth that gamble.

Solomon's own father, David, experienced not only spiritual anguish but also extreme physical distress because of his adultery. His case showed how one act of sin can lead to even more (2 Samuel 11). The so-called pleasure of adultery lasts only for a moment, but it leads to a lifetime of grief and painful consequences. Most adulterers wish they could turn back the hands of time and choose to refuse temptation.

Not only does adultery bring dire consequences to one's earthly life, it disrupts one's relationship with God. Isaiah told the people of Israel that this was a consequence of their idolatry: "Your iniquities have made a separation between you and your God" (Isaiah 59:2). Because of their sins, the Lord refused to hear their prayers. He said, "When you spread out your hands, I will hide my eyes from you; even though you make many prayers, I will not listen" (Isaiah 1:15).
