Each for the Other by Bryan Chapell. Now, it is the book that I make every young couple read through in their pre-marital sessions with me.
The premise of the book is simple. As a married couple, we each do everything for the other person. Let me explain. In Ephesians 5, the Apostle Paul gives some instructions to husbands and wives as to their responsibilities to the other person. Husbands are told to love their wives as Christ loved the church. Wives are told to submit to their husbands as to the Lord. Let me not sugar-coat these instructions. They are very difficult.
As a husband, it is could be easier for me to love my wife as Christ loved the church IF she submitted to me as to the Lord. Or, I am sure for the wife, it could be easier for her to submit to her husband as to the Lord IF her husband was loving her like Christ loved the church.
Yet, here is the standard. Here is what Chapell talks about in this book. We are called to our responsibility REGARDLESS of whether the other person is doing theirs. He calls me to love my wife as Christ loved the church not expecting anything in return. My wife is called to submit to me as to the Lord not expecting anything in return. And when we both do this together, we 100% meet each others needs. It is marriage as it's meant to be.
If you are married, this is the #1 book that I would recommend to you! Enjoy!
