If we have the Bible’s high view of sex as a picture of the Church’s union with Christ and a respect for the power God has given it, we will not only take sexual sin very seriously, but we will also examine ourselves, confess the many ways we have failed to desire and fulfill God’s perfect design, and cast ourselves again and again at the mercy of the gospel. Yes, sexual immorality is a big deal, so let’s keep pointing each other to our only faithful Bridegroom.
The temptation to single out one type of sin or one category of sinner as uniquely worthy of condemnation is common. It often springs from and feeds the self-righteous hypocrisy of our hearts, which seeks to find a point of comparison by which we can stand over another as morally inferior to us. This temptation is especially strong when the sin to which another person is tempted is one to which we feel no attraction whatsoever or which we find safely unattractive. Because we are confident that we would never do that, we find it easier to treat the person who would as particularly depraved. It is useful to our proud hearts precisely because we are sure that we are not personally susceptible to this depravity.
And yet it would be wrong for us to react to this possibility of self-righteous judgment by taking a ho-hum, cavalier attitude toward sexual sin and temptations. In the Bible, sexual immorality is a big deal. Most who are familiar with Scripture sense this. The subject of sexual immorality comes up often and is treated with heightened seriousness.
So here is our challenge: How do we understand and heed the seriousness of the Bible’s concern over sexual immorality while not giving space to our impulse to look down on others? I suggest three perspectives to help us maintain a proper biblical concern for sexual immorality without being self-righteous:
Have a biblically high view of sexuality.
In 1 Corinthians 6:12–20, Paul explains to his readers why sexual immorality is so serious: It’s because sex is so precious. Paul opens his discussion by quoting a typical cultural understanding of sex—that it is just an appetite, a biological drive to be fulfilled: “Food is meant for the stomach and the stomach for food” (6:13). Paul contradicts this directly with, “The body is not meant for sexual immorality, but for the Lord, and the Lord for the body.” His point? This is not a mere issue of appetite, a biological need for the flourishing of the human animal. Human sexuality is not primarily biological; it is theological.
This assertion alone is in radical conflict with almost all that our culture believes and teaches about sexuality. But the further we go into this truth, the more incredible it becomes. For Paul goes on to describe the content of the theology of sex, which is nothing less than union with Christ: “For, as it is written, ‘The two shall become one flesh.’ But he who is joined to the Lord becomes one spirit with him” (6:16–17). He says the same thing to the Ephesians, “’…and the two shall become one flesh.’ This mystery is profound, and I am saying that it refers to Christ and the church” (5:31–32). We have only begun to plumb the riches of biblical teaching on the ways that sex as God designed it displays to us the wonder of the salvation given to us in union with Christ.
