Let's take a look at the context.,,,,,
For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect (purge your conscience, our inner man, sanctifieth to the purifying of the flesh ). For then would they not have ceased to be offered? because that the worshippers once purged (sanctifieth to the purifying of the flesh ) should have had no more conscience of sins (sanctifieth to the purifying of the flesh) . But in those sacrifices there is a remembrance again made of sins every year. For it is not possible that the blood of bulls and of goats should take away sins (sanctifieth to the purifying of the flesh ). Wherefore when he (Jesus) cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: In burnt offerings and sacrifices for sin thou hast had no pleasure. Then said I (the writer of Hebrews or us for that Matter), Lo, I come (in the volume of the book it is written of me,) to do thy will, O God. Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; Then said he (Jesus), Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. By the which will we are sanctified (our inner man purged, sanctifieth to the purifying of the flesh )through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: (purge our conscience, our inner man, sanctifieth to the purifying of the flesh from dead works, sin, acts the cause death to serve the living God) But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected (purge our conscience our inner man, sanctified to the purifying of the flesh from dead works, sin acts the cause death to serve the living God) for ever them that are sanctified. Whereof (BECAUSE this is how they are perfected) the Holy Ghost also is a witness to us: for after that he had said before, This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more. Now where remission of these is, there is no more offering for sin. Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus (perfected, purge our conscience our inner man, sanctified to the purifying of the flesh from dead works, sin acts the cause death to serve the living God) , By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh ( The true Tabernacle, not made by hands); And having an high priest over the house (Us through the veil that is His flesh, the Body of Christ, the Temple) of God; Let us draw near with a true heart (Perfected, laws in our hearts, and in our minds) in full assurance of faith (boldness to enter into the holiest by the blood of Jesus), having our hearts sprinkled from an evil conscience (the old man purged to serve the living God), and our bodies washed with pure water. Let us hold fast the profession of our faith without wavering; (for he is faithful that promised; ) And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. For (BECAUSE) if we sin wilfully after that we have received (Getting) the knowledge (recognition) of the truth, there remaineth no more sacrifice for sins....Let us go on unto perfection (sanctified to the purifying of the flesh from dead works, sin acts the cause death to serve the living God); not laying again the foundation of repentance from dead works (sin, acts the cause death. For the wages of sins death) , and of faith toward God, Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment. And this will we do, if God permit. For it is impossible for those who were once enlightened (Illuminated, having received (Got) the knowledge (recognition) of the truth), and have tasted (experienced) of the heavenly gift, and were made partakers (sharers) of the Holy Ghost, And have tasted (experienced) the good word of God, and the powers of the world to come, If they shall fall away, (sin willfully) to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.(Heb 10:1-26; 6:1-6)
