14 For by one offering he hath perfected for ever them that are sanctified.
14 For by one sacrifice he has made perfect forever those who are being made holy.
14 For by a single offering he has perfected for all time those who are being sanctified.
14 It was a perfect sacrifice by a perfect person to perfect some very imperfect people. By that single offering, he did everything that needed to be done for everyone who takes part in the purifying process.
14 For by one offering He has perfected forever those who are being sanctified.
14 For by that one offering he forever made perfect those who are being made holy.
19 For them I sanctify myself, that they too may be truly sanctified.
19 And for their sake I consecrate myself,
19 I'm consecrating myself for their sakes So they'll be truth-consecrated in their mission.
19 And for their sakes I sanctify Myself, that they also may be sanctified by the truth.
19 And I give myself as a holy sacrifice for them so they can be made holy by your truth.
(Read John 17:17-19)
Christ next prayed for the disciples, that they might not only be kept from evil, but made good. It is the prayer of Jesus for all that are his, that they may be made holy. Even disciples must pray for sanctifying grace. The means of giving this grace is, "through thy truth, thy word is truth." Sanctify them, set them apart for thyself and thy service. Own them in the office; let thy hand go with them. Jesus entirely devoted himself to his undertaking, and all the parts of it, especially the offering up himself without spot unto God, by the eternal Spirit. The real holiness of all true Christians is the fruit of Christ's death, by which the gift of the Holy Ghost was purchased; he gave himself for his church, to sanctify it. If our views have not this effect on us, they are not Divine truth, or we do not receive them by a living and a working faith, but as mere notions.
Matthew Henry's Commentary on Hebrews 10:14
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.
