When will God's people be sealed and how? The letter to the Hebrews mentions the New Covenant Promise twice. What is it, and when will it happen? Paul in Hebrews deals with the overall picture of salvation through faith; Hebrews was written to present the complete plan of Salvation, from justification, to sanctification, through the most holy place experience and on to the reception of the promise. This book, "They Received Not the Promise," clarifies the final scenes of the purging of sin from the life of the believer. It's about the cleansing of the sanctuary, the blotting out of sins, the finishing of the mystery of God, and the latter rain. It's the complete fulfillment of the New Covenant promise of God in Jeremiah 31:31-34. The letter to the Hebrews was written to inform us of God's promise, which up to the time of Paul, God's faithful believers had "received not the promise." In Hebrews it was necessary for Paul to go through the sanctuary service showing that Christ is fully God and man, Our High Priest who died for us; He is now working for the saving of our souls and the "perfecting of the saints."
