Bestselling author Larry Crabb cuts to the heart of the biblical view of marriage: the "one-flesh" relationship. He argues convincingly that the deepest needs of human personality--security and significance--ultimately cannot be satisfied by a marriage partner. We need to turn to the Lord, rather than our spouse, to satisfy our needs. This frees both partners for "soul oneness," a commitment to minister to our spouse's needs rather than manipulating them to meet our own needs. With "soul oneness" comes renewed "body oneness," where couples enjoy sexual pleasure as an expression and outgrowth of a personal relationship.
