But the foundation of it all is the Bible.
Plenty of people who do not acknowledge God or the Bible, yet who are experiencing happy marriages, are largely abiding by God’s intentions, whether they realize it or not. But it is far better if we are conscious of those intentions. And the place to discover them is in the writings of the Scripture.
