How long does Christ's one offering keep believers perfected?
Christ's one offering keeps believers perfected forever. Scripture says He has perfected forever them who are sanctified. This permanence does not depend on human performance or stop when a believer stumbles, sins, or drops the ball; it remains forever because His sacrifice fully secured it.
Les explains that the passage contrasts the repeated work of every priest, who stood daily ministering and offering the same sacrifices that can never take away sins, with the Christ. After He offered one sacrifice for sins forever, He sat down on the right hand of God. By that one offering He has perfected forever them who are sanctified. How long? Forever. Forever. Not until we goof it, not until we drop the ball, but forever.
