The author again quotes from Jeremiah 31:33–34 (see Hebrews 8:7–12) to support the statement in 10:14. This shows that Christ’s one sacrifice under the new covenant has made worshipers perfect forever.
God’s laws have now been placed in their hearts and on their minds. This means that a believer’s relationship with God is now inward, not just outward.
Their sins and lawless acts I will remember no more: As the author has shown in 9:11–10:14, this is possible only because Christ’s sacrifice is greater than all others.
