Covenant in My blood” (Lk. 22:20; Mk. 14:24), how can the unregenerate children of believers be said to be “in” the New Covenant, church, and kingdom without an effectual Mediator? They cannot. Indeed, Hebrews 9:15 defines Christ as an effectual Mediator of the New Covenant to insure that “those who are called may receive the promise of the eternal inheritance.” Can one be said to be “in” the New Covenant or church without a Mediator? Not on the basis of the concept of the church in the New Testament.
