This book by Dr. Emerson Eggerichs puts forth the one major concept that I feel is lacking in many marriages today. It's a conclusion that my husband and I had finally come to - though not in these exact terms - so reading it so clearly put really helped solidify and strengthen things in our marriage.
I feel that every married couple would benefit from reading and applying these principles. If husbands reached out in unconditional love, speaking and acting in love, wives would respond with greater respect. If wives gave unconditional respect, speaking and acting in respectful ways, husbands would respond with greater love. It's a cycle that actually works and that I have seen first hand in my own marriage.
This isn't about "submission" or about anyone being "in control" in a marriage. It is simply about the built-in needs of a man and a woman, and how to best meet those needs.
To anyone who is hesitant about trying these ideas, or who feels that there's a great risk involved, I would say TRY IT. I promise that you will see and feel the good results.
