Read 2 Samuel 11:2-3
Then it happened one evening that David arose from his bed and walked on the roof of the king's house. And from the roof he saw a woman bathing, and the woman was very beautiful to behold. So David sent and inquired about the woman. And someone said, "Is this not Bathsheba, the daughter of Eliam, the wife of Uriah the Hittite?"
In December 1985 an enormous sinkhole swallowed a house and carport and forced the evacuation of four homes in a retirement community in Florida. The hole was about the size of a pickup truck when it was discovered. Within three hours it had grown to 30 by 40 feet and had swallowed half of a small house. Two hours later it had expanded to more than 70 feet, and the house with its carport was gone. Authorities were grateful that it finally stopped growing without doing even more damage.
David discovered that sin is like an ever-expanding sinkhole. As he was walking on the flat roof of his palace, he saw a beautiful woman bathing. Instead of turning away, he stared longingly at her. At this point the sinkhole was small but expanding. When he inquired about who she was, the hole grew larger. And finally, when he sent for her (v. 4), he soon found himself and those around him swallowed up. What started out as only a look ended in tragedy for all involved.
The best solution for avoiding the danger of a sinkhole is to stay far away from it. The same is true for sin. A lingering look, a carnal curiosity and the sinkhole of sin can rapidly expand. And once it starts to grow, the damage can be extensive. Your marriage, your morals and even your relationship with the Lord can be swallowed by its gaping mouth. Before you even have time to realize what's happening, everything you value might be gone.
Don't lose what's important to you down a sinkhole. Flee sin before it can swallow you and those you love. The farther away you stay from sin, the safer you are.
The sinkhole of sin is never satisfied.
