Is there a secret to a successful marriage? Derek Prince believed so, and that this secret is found in the pages of the Bible. Prince discusses the "mystery" of marriage as God established it at creation, and as Jesus restored it through the New Covenant. His exposition combines the profound and the simple in a way that brings God's highest within the reach of every sincere seeker. He goes on to show how the basic principles also make true spiritual union possible between each believer and God, and between fellow believers.
