And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins.  (12) But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, (13) from that time waiting till His enemies are made His footstool.  (14) For by one offering He has perfected forever those who are being sanctified.   (18) Now where there is remission of these, there is no longer an offering for sin. 

The Levitical priesthood stands – literally stands as there were no chairs in the place of sacrifice.  This peculiarity and the continued ministry of the priests is symbolic of their work never being finished.  The problem with the sacrifice of the priests was not so much with the sacrifices but with the giver of the sacrifice.   Their repeated sacrifices could NOT finally remove sin.  The old priesthood is contrasted to our new High Priest, Jesus Christ, who offered Himself, a voluntary blood sacrifice, once and for all.  This perfect offering completely removes the guilt of sin.  After this perfect offering, Christ sat down at the right hand of power. The sitting of Christ indicates that His work of offering sacrifice is done – it was/is perfectly complete.  God honors His Son with the seat at His right hand to show His satisfaction with the debt paid for sin.  All who accept His offer of salvation receive complete forgiveness and eternal life.

The author of Hebrews wrote his letter as a subtle – or not so subtle – warning to his audience that if they abandoned their Christian faith and went back to Judaism they would be enemies of Jesus.  We are all enemies of God – we toward God in rebellion and He toward us in wrath.  Man is the enemy of God, not the reverse.  The hostility must be removed from man for reconciliation.  God took initiative in this by sending His Son to die for us and this reconciliation is put as strongly as possible.  The divine acceptance of that sacrifice – Christ being seated at the right hand of the power – shows the rightness of Christ as the perfect High Priest.  God now remembers the sin no more, forever.  A sinner can once for all believe and be saved.   Everything essential to the salvation of the individual is included in the gift for salvation which the sinner receives by faith in the Messiah’s sacrifice.

Verse 14 is the conclusion of the doctrine of the Epistle to the Hebrews.  By one offering Christ has perfected forever those who are sanctified – cleansed from sin.  He has perfected them – finished and completed for the sanctified all they need.  This perfection is forever.  This verse speaks of the believer’s sanctification as an accomplished fact – those are saints, holy in Christ.  Just by faith we can enter into Christ’s fullness.   What more can we need??????   There is no more need for symbolic work- the real atoning work and forgiveness is perfect.
