I also have something to say to everyone else. It is from me, not a direct command from the Lord. Suppose a brother has a wife who is not a believer. If she is willing to live with him, he must not divorce her.
The unbelieving husband has been made holy through his wife. The unbelieving wife has been made holy through her believing husband. If that were not the case, your children would not be pure and “clean.” But as it is, they are holy.
