Marriage begins with "I do" but "I do" what? The commitments spouses make to one another on their wedding day are the beginning of a lifelong process of spiritual and relational growth. Wayne Barber teaches 8 keys that unlock doors to marriage success. Each key opens one door, yet all 8 keys are on the same key ring. Together, these 8 keys open doors in the house that builds the marriage God desires. These 8 lessons can encourage your personal study, study with your spouse, or can be used in small groups.
