This book is a study of the marriage covenant. It describes its origins, established by God in the Garden of Eden. The husband and wife lived in complete harmony with God and with each other. Their disobedience to God destroyed this harmony: this is the origin of the conflicts experienced by all couples on earth. This book teaches men and women to discover their potential as men, husbands and fathers, and women as women, wives and mothers. Husbands-to-be and husbands discover their rights and responsibilities as established by God. They learn about agape love, which is different from friendship and sexual attraction. The book also helps them to deal with the challenges of living together with a stranger and to manage their priorities. This book is therefore a vade mecum for a harmonious life in the couple and the family, where God pours out his blessing that brings prosperity and is not accompanied by sorrow.
