Be Faithful

What is adultery? The writers of the New Testament use the Greek word porneia, which translates to “pornographic” or “immorality.” The word refers to adultery, which is extramarital sex. It refers to fornication, which is premarital sex. It refers to homosexuality. It refers to incest, molestation, and even bestiality. All these things figure into the seventh commandment. God is saying, “You must not do this.”

Imagine what kind of world we would live in today if this single commandment was obeyed. How many marriages would still be intact? How many fathers would still be at home? How many divorces would have been averted? I believe that historians and sociologists looking back on our era one hundred years from now will say that we were a culture obsessed with sex.

Having said that, though, I must also emphasize that sex is not sinful in and of itself. Remember, God created sex. But why? Some would say for procreation. Period. That childbearing is its only purpose. But that’s not what the Bible teaches. The Bible makes it clear that God gave us this wonderful, pleasurable expression of love to be made from a man to a woman and from a woman to a man within the safety of a marriage relationship. Any other variation of it is wrong.

When a man and woman have sexual relations together, a oneness takes place. Paul wrote about it in 1 Corinthians 6:15–18: “Don’t you realize that your bodies are actually parts of Christ? Should a man take his body, which is part of Christ, and join it to a prostitute? Never! And don’t you realize that if a man joins himself to a prostitute, he becomes one body with her? For the Scriptures say, ‘The two are united into one.’ But the person who is joined to the Lord is one spirit with him. Run from sexual sin! No other sin so clearly affects the body as this one does. For sexual immorality is a sin against your own body” (NLT).

So, no one can say, “It was just a one-night fling. It didn’t mean anything to me.” That’s not what the Bible says. No one can say, “As long as it’s between two consenting adults, no one gets hurt.” The Bible teaches that every time we commit sexual sin, someone else gets hurt.

One day, if you live a long life, you may be sitting in a rocker on the front porch of a retirement home, thinking back on your days. In that moment, I don’t think that you’ll care all that much about how successful your career was, or what your income level was, or how great your accomplishments were. But you will celebrate the fact that you were faithful to your spouse and that your marriage stood the test of time. And in that moment, you’ll know why God gave you the seventh commandment: “You must not commit adultery.”
