When He hath by Himself purged our sins sat down !3
Again, who are the " Our Sins" of Heb 1:3
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:
We showed that it was church previously and we showed and go back to that it's the Seed of Abraham, that follows within the overall context of Hebrews, written specifically to the Seed of Abraham Heb 2:16-17
16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
17 Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.
He took on the Seed of Abraham to make Reconciliation or Propitiation for that particular People !
Took on Him actually means Heb 2:16
16 Clearly, it is not angels that Jesus helps. He helps the people who are from Abraham. ERV
16 For surely it is not angels that he helps, but he helps the offspring of Abraham.ESV
People say that's all ethnic jews ? That's wrong, its all believers in Christ, His Body the Church, jew or Gentile Gal 3:29
29 And if you belong to Christ [are in Him Who is Abraham’s Seed], then you are Abraham’s offspring and [spiritual] heirs according to promise. AMP
That's the Our Sins of Heb 1:3, why wouldn't be ? Who is more important to a Man than His Wife of whom He is One Flesh ? Eph 5:25-26
25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
26 That he might sanctify and cleanse it with the washing of water by the word,
Now If Christ is the Seed of Abraham Gal 3:16, then how could His Wife the Church , whom He is One flesh with, not be the Seed of Abraham ? Lets read Eph 5:30-32
30 For we are members of his body, of his flesh, and of his bones.
31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
32 This is a great mystery: but I speak concerning Christ and the church.
So quite reasonably the Flesh and Blood of His Brethren here Heb 2:14
14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
Abraham's Wife was actually His Sister also. Gen 20:12
12 And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.
So Likewise, Christ the Seed of Abraham, His Wife[His Bride] is also His Brethren Heb 2:16-17
16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
17 Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.
Its His Bride the ChurchThe Seed of Abraham that is the Our Sins of Heb 1:3, and Vs 17 of Heb 2:17 is but a commentary of Heb 1:3 as well as 1 Cor 15:3.
Finally this purging of sin Heb 1:3 is a completed and accomplished work, it has noting to do with the acts or actions of those who are the Seed, it does not depend on their believing it, accepting it, their behavior or their sinful state, its a True fact even when they are in unbelief and rebellion and rejection of God. Regardless, God views them in the eyes of His Law as Not Guilty of one sin against His Law. As a result of Christ's purging our sins, it fulfills completely and finally what was only temporal and incomplete as a result of the offerings on the day of Atonement for the sins of the People Lev 16:30
30 For on that day shall the priest make an atonement for you, to cleanse you, that ye may be clean from all your sins before the Lord.
Yes, Christ's purging of Our sins, if He died for us indeed, Gives God to view us as here indicated Col 1:22
22 In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: 21
