At some point, we have all witnessed the devastation of an affair. On the one hand, it is shocking just how much can be destroyed by the act of one person sharing sexual intimacy with another. But on the other hand, it is not shocking at all when we consider how much meaning God has packed into marriage and into the sexual relationship within marriage. One of the great misconceptions about affairs is that they begin with sex. Affairs do not begin with sex. Falling into bed with a man who is not your husband or a woman who is not your wife is never a sudden, unplanned event. Instead, it is a culminating decision in a long list of terrible, self-centered decisions.
Some time ago Denny Burk and I spoke at a conference, and Denny told us about the 6 "e's" that Tommy Nelson uses to describe the "ease" with which people fall into extra-marital affairs. I have shared them before but thought it might be helpful to share them again. I believe any married man or woman can benefit by occasionally considering them. Consider it one more means to fulfill 1 Timothy 4:16: "Keep a close watch on yourself and on the teaching." (I will write from a male perspective, but it works equally well if you reverse the pronouns.)
Affairs do not begin when you experience sexual intimacy with someone who is not your spouse. An affair begins much farther back, when you begin to eliminate intimacy in your marriage. This is not only the intimacy of sex, but the intimacy that comes by dating, by long face-to-face conversations, and by physical affection. Instead of pursuing your wife, you grow hard and complacent. The joy fades, the discontentment rises.
