David Clarke writes on the premise that there are 3 aspects in a Christian marriage:Physical BondingEmotional Bonding andSpiritual BondingHe informs us how to become Spiritual bonded and how when we do that as a couple it improves our marriage and increases the other 2 aspects of bonding in a marriage.The first part of the book is a little repetitive as he is writing about why we need the be spiritually bonded to our spouse, but the second part of the book gets to the meat of the matter and gives really good applicable advice on how to be spiritually bonded and ways this can truly happen. Great book - that I recommend for all Christian couples - by the way don't just read it - apply it!
