Christians married to unbelievers were not to worry that they themselves, their marriage, or their children would be defiled by the unbelieving spouse. On the contrary, the very opposite was the case. Both the children and the unbelieving spouse would be sanctified through the believing wife or husband.Being unequally yoked, one flesh with an unbeliever, can be frustrating, discouraging, and even costly. But it need not be defiling because one believer can sanctify a home. In this sense sanctify does not refer to salvation; otherwise the spouse would not be spoken of as unbelieving. It refers to being set apart, the basic meaning of sanctify and holy, terms that are from the same Greek root. The sanctification is matrimonial and familial, not personal or spiritual. In God's eyes a home is set apart for Himself when the husband, wife, or, by implication, any other family member, is a Christian. Such a home is not Christian in the full sense, but it is immeasurably superior to one that is totally unbelieving. Even if the Christian is ridiculed and persecuted, unbelievers in the family are blessed because of that believer. One Christian in a home graces the entire home. God's indwelling that believer and all the blessings and graces that flow into the believer's life from heaven will spill over to enrich all who are near...
