What is the cabinet by Mark Johnson is a very good read that takes a deep look at what a covenant truly Is.

The books Product description says:
“The world is attempting to redefine Marriage and a relationship with God in accord with ever-shifting cultural views. In sharp contrast, God has had a specific plan for these two relationships in place from the beginning. Both are termed Covenant Relationships. There is little current teaching in the Christian community about the structure, function, and purposes―or even the definition―of these relationships.“

I learned a lot from this book and truly believe many in the church would benefit from reading it as well, especially the young adults.
