(Pro 6:26 KJV) For by means of a whorish woman a man is brought to a piece of bread: and the adulteress will hunt for the precious life.
Wasted money. Wasted resources. Wasted lives. This is a reminder that God expects us to be stewards of what we have. The context is sexual sin but I don’t think the words necessarily mean prostitutes. I think the context works just as well with the casual fling. It is so easy to throw away everything we have built up in life and do it in a moment.
Here the danger is sex outside of marriage. It could just as well be going for that one time shady business deal that is going to set you up and you promise not to do it again. It could be the lie that gets you out of a tight spot but comes back to bite you.
So? Forgiveness is available. Grace is a gift. God is patient. He also is not big on playing games and you can’t fool Him.
