* "For Men Only" & "For Women Only" Shaunti and Jeff Feldhaln – A straightforward guide, easy read to the inner lives of men and women. One probably can finish this short book in less than 1 or 2 hours. Also written by the couple is For Women Only which I recommend as well. These books helped the wife and I as we worked through our first couple years of marriage. Each one is a great short read that is very insightful! I highly recommend it!
* "Love & Respect" - Dr. Emerson Eggerichs – This is recommended by Focus on the Family. This book reflects primarily on Ephesians 5:33 “Nevertheless let each one of you in particular so love his own wife as himself, and let the wife see that she honors her husband.”
He goes onto explain that men often speak one language and women another. Women see through pink glasses, hear through pink hearing aids, and speak through a pink megaphone. Men on the other hand see through blue glasses, hear through blue hearing aids, and speak through a blue megaphone. It is learning to speak each other's language and seeing the other person's perspective that really makes the difference.
I definitely recommend this book and have even have given a copy to a friend.
These are two that we enjoy and have helped us. I'm sure there are others I can't think of at the moment.
