“Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? Whosoever, therefore, will be a friend of the world is the enemy of God” (James 4:4).
When I was a kid, I used to go the fair. It was a big deal in those days. We would have a great time eating cotton candy, riding the little Ferris Wheel, playing games in the arcade, and walking on the sawdust. When you went to a fair, you left all the responsibilities of normal life behind, at least for a little while. Life was lots of fun at the fair.
Maybe that is the reason why some call an adultery an affair. It’s leaving behind your responsibilities. Real men do not leave their places of responsibility. Real men do not have affairs with other women. Nor do real men have an affair with the world around them. They know it is the cause of being at hostility against God.
What is an affair? It is an escape from reality, or a search for meaning outside of marriage, either to your mate or even to Christ. God said do not become an adulterer or adulteress with the world. Do not join up with the things of this world. Do not have an affair with the world and leave your responsibilities behind.
