The issue of marriage within the church—namely the noticeable lack of distinction between Christian and non-Christian marriage, given our equal propensity to divorce—is not about the preservation of a tradition or institution. The reality of marriage and our apparent lack of respect for that which "God has joined together" ultimately reveals a gaping chasm between biblical Christianity and cultural Christianity that must be closed if the church wants to be faithful to its mission.

I am convinced that the recent diminution of marriage—both within the church as well as in the culture-at-large—originates in a fundamental theological misunderstanding among many Christians.

As I (and many others) have begun to argue recently, the gospel of the kingdom has—over the last century or more—suffered a serious reduction to little more than a privatized prescription for personal salvation. Among other things, this severance from the kingdom has resulted in an undue emphasis on the individual's eternal blessing in the future (i.e., saved from hell), rather than on the Savior and his present kingdom that orders and directs our daily lives. As a result, we tend to live and remain largely within ourselves—citizens of this world—never really working to advance the kingdom in a meaningful, biblical way. 

The apostle Paul, writing to the Philippians, urged them to "let your manner of life be worthy of the gospel of Christ" (Philippians 1:27, ESV)—and according to the Scriptures, the gospel of Christ is the good news of his in-breaking reign or kingdom. This theme is better reflected in the original Greek, which can be translated as, "Only behave as a citizens worthy of the gospel of Christ." This better captures Paul's play on words here and later in Philippians 3:20 when he writes, "our citizenship is in heaven" (NKJV). Later in the same sentence, Paul emphasizes "standing firm in one spirit, with one mind striving side by side for the faith of the gospel (v. 27). In the very next verse, Paul explains that this unity is a "clear sign to them of their destruction, but of your salvation, and that from God" (v. 28). Paul is stressing our responsibilities associated with our new citizenship in the kingdom and that this foreign citizenship is essential to the witness of the church.

In his excellent series addressing "the vexing question of God's goodness and the presence of real evil in the world," my good friend Dr. John Armstrong quotes Dr. David Bryant, a mutual friend and author of Christ is All! Speaking to the problem of our anemic kingdom perspective, David says:

We speak of Christ's greatness in the past tense and in the future tense but rarely do we speak of it in the present tense. We speak of his work of redemption and of his coming again to judge and to save. But too few of us speak of his greatness right now, i.e., in the present tense. [I suggest] that Christ's kingship does not come up in Christian conversations and living because, for all intents and purposes, he is not a part of our daily lives. This is why we do not see Christians pursuing a "purpose driven life" because the Person who gives our lives real purpose does not presently reign in our understanding and affections.
