In such a separation, the two are still marriage mates and, even though living apart, would still face challenges. The apostle Paul gave this reason for staying united: “The unbelieving husband is sanctified in relation to his wife, and the unbelieving wife is sanctified in relation to the brother; otherwise, your children would be unclean, but now they are holy.” (1 Cor. 7:14) Many loyal Christians have remained with an unbelieving mate under very trying circumstances. They can testify that doing so was worthwhile in a special sense when their mate became a true worshipper. (1 Cor. 7:16; 1 Pet. 3:1, 2) Worldwide today, the Christian congregation abounds with successful marriages. You can likely find many happy couples in your local congregation. They are made up of loyal brothers who love their wife and devoted wives who prove to be loving mates, all showing that marriage can be honorable.​—Heb. 13:4. w18.12 14 ¶18-19
