Heb 9:13-28. PROOF OF AND ENLARGEMENT ON, THE "ETERNAL REDEMPTION" MENTIONED IN Heb 9:12.

      For His blood, offered by Himself, purifies not only outwardly, as the Levitical sacrifices on the day of atonement, but inwardly unto the service of the living God (Heb 9:13, 14). His death is the inaugurating act of the new covenant, and of the heavenly sanctuary (Heb 9:15-23). His entrance into the true Holy of Holies is the consummation of His once-for-all-offered sacrifice of atonement (Heb 9:24, 26); henceforth, His reappearance alone remains to complete our redemption (Heb 9:27, 28).

      13. if--as we know is the case; so the Greek indicative means. Argument from the less to the greater. If the blood of mere brutes could purify in any, however small a degree, how much more shall inward purification, and complete and eternal salvation, be wrought by the blood of Christ, in whom dwelt all the fulness of the Godhead?
      ashes of an heifer-- (Nu 19:16-18). The type is full of comfort for us. The water of separation, made of the ashes of the red heifer, was the provision for removing ceremonial defilement whenever incurred by contact with the dead. As she was slain without the camp, so Christ (compare Heb 13:11; Nu 19:3, 4). The ashes were laid by for constant use; so the continually cleansing effects of Christ's blood, once for all shed. In our wilderness journey we are continually contracting defilement by contact with the spiritually dead, and with dead works, and need therefore continual application to the antitypical life-giving cleansing blood of Christ, whereby we are afresh restored to peace and living communion with God in the heavenly holy place.
      the unclean--Greek, "those defiled" on any particular occasion.
      purifying--Greek, "purity."
      the flesh--Their effect in themselves extended no further. The law had a carnal and a spiritual aspect; carnal, as an instrument of the Hebrew polity, God, their King, accepting, in minor offenses, expiatory victims instead of the sinner, otherwise doomed to death; spiritual, as the shadow of good things to come (Heb 10:1). The spiritual Israelite derived, in partaking of these legal rights, spiritual blessings not flowing from them, but from the great antitype. Ceremonial sacrifices released from temporal penalties and ceremonial disqualifications; Christ's sacrifice releases from everlasting penalties (Heb 9:12), and moral impurities on the conscience disqualifying from access to God (Heb 9:14). The purification of the flesh (the mere outward man) was by "sprinkling"; the washing followed by inseparable connection (Nu 19:19). So justification is followed by renewing.
