The curriculum The Oneness of Marriage, created by Dr. David & Terri Sumlin, is designed to help couples embrace God’s design for marriage in a way that gives them practical tools to disarm the threats to marital oneness and reclaim surrendered oneness. It is broken down into 5 sessions and this unique approach to marital enrichment is built upon some of the advances found in neuroscience, psychology, physiology, and adventure-based therapy, which ultimately is tested through the lens of God’s word for validation.
