Sex | Biblical Message #2

I've been sharing excerpts from my sermon for high school students about sex, some of which was influenced by a sermon from Tim Keller. Using 1 Corinthians 6:12-20 as my text, I've written about the two cultural myths about sex: 1) I can do whatever I want with my body; and 2) Sex is just an appetite. This post will lay out the biblical message that counters the second myth.

Sex is not just an appetite. That is such a low, degrading view of sex. Look at this passage again. Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.”

Don’t get caught up by the word prostitute. In those days you were either married or you were a prostitute. Christianity was the first social movement, religion, or institution to ever say, “It’s okay to be single.”

But Paul is quoting the book of Genesis here, and he’s saying whenever you have sex with someone, you become one flesh with them. Well, what does that mean? Perhaps you’ve heard of the phrase “the beast with two backs”? Well, that’s not what it means. The word “flesh” can mean a couple of different things, and in this instance what it means is “embodied personhood”. It means “full humanity expressed in your body”.

Sex is not about becoming one body with your sexual partner, it’s about giving your full humanity to another. Sex is the donation of your full humanity to another. This is the biblical message that counters the cultural myth “sex is just an appetite.”

God designed sex to be the consummation of a host of commitments that you make to your spouse. It’s the last commitment, the one in which you physically live and embody all of those commitments—the social, the legal, the relational, the responsibility, the mental, the spiritual, and the emotional.

There is no such thing as casual sex. There is no such thing as sex with no strings. That’s the fantasy of a screenwriter. Sex without those commitments is dehumanizing. Casual sex makes you less human; it turns you into an object of another person’s lust. It is not embodied humanity, it is embodied pornography. It is false.
