make officially VALID.

however,
there are many pew people
—including some theologians
—who do not truly grasp the significance of the New Covenant.
Because of this, they have failed to instill the church with some of the most important, life-changing teachings that are inherent in the New Covenant.
The result is that many Christians lay claim to the New Covenant, but they actually believe that it is merely a warmed-over Old Covenant

Failure to distinguish properly between the two covenants has caused many Christians to live according to the Old Covenant, while thinking they are under the New Covenant.
Because of this, many sincere Christians continue to be troubled by guilt, feelings of failure and inadequacy, and others use the New Covenant to claim the right to sin that grace may abound (Rom. 6:1).
