12 but he, when he had offered one sacrifice for sins forever, sat down on the right hand of God; 13 from that time waiting until his enemies are made the footstool of his feet. 14 For by one offering he has perfected forever those who are being sanctified. 15 The Holy Spirit also testifies to us, for after saying, 16 “This is the covenant that I will make with them:
‘After those days,’ says the Lord,
‘I will put my laws on their heart,
I will also write them on their mind;’” [1]
then he says, 17 “I will remember their sins and their iniquities no more.” [2] 18 Now where remission of these is, there is no more offering for sin.

Commentary on Hebrews 10:11-18
(Read Hebrews 10:11-18)
Under the new covenant, or gospel dispensation, full and final pardon is to be had. This makes a vast difference between the new covenant and the old one. Under the old, sacrifices must be often repeated, and after all, only pardon as to this world was to be obtained by them. Under the new, one Sacrifice is enough to procure for all nations and ages, spiritual pardon, or being freed from punishment in the world to come. Well might this be called a new covenant. Let none suppose that human inventions can avail those who put them in the place of the sacrifice of the Son of God. What then remains, but that we seek an interest in this Sacrifice by faith; and the seal of it to our souls, by the sanctification of the Spirit unto obedience? So that by the law being written in our hearts, we may know that we are justified, and that God will no more remember our sins.
