Marriage has existed in different forms in all cultures of the world according to the existing traditions in the cultures for procreation and the continuation of life on earth. The Garden-Marriage Principles look at marriage in different cultures--Bible cultures and other traditional cultures, industrial cultures, contemporary cultures, and the likely cultures of tomorrow's world. From the cultures at the beginning of creation in the Bible, it looks at the aim and purpose of marriage as intended by the Creator.

The book suggests that marriage is a training ground, just like the church, for the preparation for the Christian hope in the marriage supper of the Lamb. This is the mystery that Paul talked about: "This is a great mystery; but I speak concerning Christ and the church" (Ephesians 5:32). To be successful in marriage, the couple must understand the roles and responsibilities of each of the spouses and work to meet the expectations, demands, and responsibilities they have to God.

Looking through the various progressive cultures, the book looks at the various deviations there have been in marriage that could still be in the evolving cultures of the world. Because many do not understand the mystery, many live for self and by sight. Because they do not understand the love of God, they live in the deceit and consequences of the fall in the garden.

The book teaches that the Christian home has the responsibility to educate the coming generations and prepare posterity for the roles of meeting the God-given responsibilities to humanity and prepare everyone, even from very early stages of life, for the marriage supper of the Lamb. The book extols the love and mercies of God to all who would hear and listen to his will, so long as it is still called today. No matter their state and status--single, married, divorced, etc.--he still says, "Come. And let him that is athirst come. And whosoever will, let him take the water of life freely" (Revelation 21:17b). And it teaches how.
