A overriding purpose of grace

I believe that there are covenants that can be classified as a “covenant of grace“, but I cannot hold biblically to an actual covenant of Grace, since it is not revealed in scripture explicitly and clearly.  I am OK with using the description “covenant of grace” to denote God’s gracious purpose over all covenants as well.  God does have a “purpose of grace.”

John Zens talks about this in:  Is There A “Covenant Of Grace?”
