I was also going to point out abuse as a big issue in marriages. Some Christian men, wrongly reading the Bible, think that they are masters and their wives are slaves. This inequitable relationship is always going to end in divorce. Or death of the victim!
Abuse is about controlling someone else. So, it is not just about physical abuse, but financial, emotional, social, child rearing, sexual and many other issues. Mostly, a combination of one or more. An abuser is not going to try and control someone in just one area of their lives. Instead, the need to control spills over into many areas. And violent person is going to end up physically abusing their spouse, which is the final straw in destroying a marriage relationship.
No person should have to endure continuous abuse at the hands of someone who is supposed to love them.
"Husbands, love your wives, as Christ loved the church and gave himself up for her,26 that he might sanctify her, having cleansed her by the washing of water with the word,27 so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish.28 In the same way husbands should love their wives as their own bodies. He who loves his wife loves himself.29 For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church,30 because we are members of his body." Eph. 5:25-30
Christ never controlled or abused his church. And to say the husband NEEDS to control his wife, because she is not behaving, is a total twisting of marriage. Marriage is not about the husband disciplining the wife, as one would a child. Instead, it is a mutual relationship of caring, sharing, helping and loving.
A good book to read on this topic is "A Cry for Justice" by Jeff Crippen, a pastor. He was counselling women to go back to their husbands and love them more. What he ended up with, was dead wives. Because an abuser needs more help than just his wife obeying his every whim. In fact, deep repentance and counselling are needed, for God to effect a change. Of course, this also applies to men who are abused! Although men are generally stronger, a woman with a baseball bat or even a gun, can do as much damage as any strong man! I do remember one profound comment in the book. It was concerning one woman who was getting beaten daily by her husband, because she did everything right! He said she was "too perfect." Because, any excuse is viable in the eyes of an abuser.
My point! No one should stay in an abusive marriage. Then need to get out, then see if the abuser is willing to change. And then, only reconcile after extensive counselling and/or marriage counselling. Abusers can change with the help of God, but it is something they have to want to do! And they have to work hard to change controlling attitudes and actions.
And, I guess the other question should be asked, is that is a person who abuses their spouse, truly a Christian? Of course, that is between them and God, but, in the case of abuse, the spouse who is being abused needs to ask this hard and fast question, and find out if they need to leave an unbeliever, or seek counselling if that person thinks they can change.
