(Proverbs 9:17 KJV) Stolen waters are sweet, and bread eaten in secret is pleasant.
From what I hear, sin is fun. Of course I have no first hand knowledge...., right. One of the lines I have heard before is that if it is fun or enjoyable, it is a sin. That is obviously not the whole story and impossible to be true. Life is full of fun, fulfilling activities that we can participate in and still be righteous. In spite of that we tend to focus on the few things that we are not allowed to do.
When I went to watch my daughter ride in a rodeo it was fun and up to God’s standards. It wasn’t so much fun watching her fly off the horse and hit a fence, but no harm, no foul. When my son beat the sox off of me playing fussball, it was fun and God probably enjoyed it more than I did. He didn’t lose. The list is only limited by your imagination.
So? Keep the big picture in mind. Sin may be fun now but the payoff has some serious drawbacks.
