The divorce courts eat up the financial resources of those whose marriages fail due to adultery. Often houses must be sold below the market price to make quick settlements. This is one of the least of the reasons why adultery is bad but it does count for something. After all, we spend a lot of our time earning money. It seems to just be the way it is that whoever you sleep with gets your money.
Prostitutes know that.
A whole industry has grown up around that fact. You may not believe that the devil exists, but I'm telling you, you will see the results of his influence if you commit adultery. He then has a legal right to put a curse on you. Evil spirits will steal your peace, joy - possibly even your health and life. The good news of Jesus Christ means that anyone caught in sexual sin can experience forgiveness and restoration.
