Our adoption was before the foundation of the world. This is because the New Covenant was established at the cross and in that covenant, our names were written into the will. When Jesus died, the will was enacted and our names were found in the will, making us children of God with Christ Jesus being the firstborn whose inheritance is first and foremost.
We are found, in Christ. Which means that when Jesus became our substitute, God the Father see's our position as righteous because we are crucified with Christ and no longer live.
I can agree with the first paragraph.
The second you see Christ as a substitute, were I see no substitution necessary, but the imputing of righteousness to us by the work of the crucifixion.
Btw, I am also not greatly enamored by the term "impute" for it has a rather negative connotation that one is wrongly accused or wrongly punished.
Yet, it does fit going the other direction as one who is pardoned of a judgement. There was not the substitution, the judge, jury, executioner, did not substitute (stand in for ) the sentence, but the governor, the one who signs into law proclaimed pardon. That was what was done by the work of the crucifixion. Again - not substitution, for we are still sinners saved by the unmerited favor of God.
Our deserved wrath is received upon the Lamb of God in his crucifixion. The debt of our sin was paid, once and for all, through Jesus atoning sacrifice. This is the argument of the speaker to the Hebrews as he connects the Old Covenant sacrifices as foreshadowing the New Covenant sacrifice of Christ Jesus on the cross.
Yet, there is no Scripture support for this assertion of "our deserved wrath received upon the Lamb of God in his crucifixion," that I can find. I would be glad to see it. But so far, it is not found. It doesn't occur even by inference much less statement in Hebrews.
The wrath of God was satisfied in Christ. "There is now no longer any condemnation for those who belong to Christ."
Romans 8:26-39 brings this truth home.
Romans 8:
26In the same way, the Spirit helps us in our weakness. For we do not know how we ought to pray, but the Spirit Himself intercedes for us with groans too deep for words.
27And He who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God.
28And we know that God works all things together for the good of those who love Him, who are called according to His purpose.
29For those God foreknew, He also predestined to be conformed to the image of His Son, so that He would be the firstborn among many brothers.
30And those He predestined, He also called; those He called, He also justified; those He justified, He also glorified.
31What then shall we say in response to these things? If God is for us, who can be against us?
32He who did not spare His own Son but gave Him up for us all, how will He not also, along with Him, freely give us all things?
33Who will bring any charge against God’s elect? It is God who justifies.
34Who is there to condemn us? For Christ Jesus, who died, and more than that was raised to life, is at the right hand of God—and He is interceding for us.
I carefully read these words when a child and rejoiced at the planning of my Father.
However, there is not the hint of "The wrath of God was satisfied in Christ" in this passage. Again, not even an inference much less actual statement.
We, by nature of being chosen...AND by Jesus atoning sacrifice for our particular sins, have been, am, and will be saved.
Just being written in the book of life is not enough. An atonement for my sins must be made and that atonement is made by God the Son on my behalf as a substitute for my sins.
"Just being written in the book of life is not enough." is a very alarming statement!
Whoever does not have their name written in the book of life is cast into the Lake of Fire according to Revelation 20.
Atonement for sins certainly. There is no disagreement. But was the yearly atonement sacrifice ever considered a substitutionary sacrifice in the OT?
Here is the difficulty with the substitute thinking. If one is a substitute, they replace the archetype with a temporary or forgery. This is seen by your Hebrews quote earlier. Christ is the archetype and all the others were temporary (forgery) in which were not completely pleasing to God and only temporary assuaging Him. Yet, He showed not wrath.
At the crucifixion, permanent effect was made, not by a substitute, but by the very archetype of which all other sacrifices were copies.
There absolutely was a need, because until Jesus died as the perfect atoning sacrifice for my sins, God's wrath was upon me. Yes, my position was secure before the foundation of the world, but the atoning work of Christ was still necessary. This is why the speaker to the Hebrews tells us about the faith of those who came before Christ, who by faith looked forward to their Redeemer who would pay the price for them. If, their sins were already paid for, there would have been no need for Christ Jesus to come and die on the cross.
Was it? Was God's wrath upon you? Why? If Christ took all wrath at the crucifixion as you hold, why then 2000 years later does God have wrath? Did He forget? I jest. But yet it remains a rather serious presentation. For either the work of the crucifixion is complete, and we may at our appointed time enter His rest (Hebrews 4 or 5) or it was incomplete and waiting upon human timing.
The folks looking forward were not in a place of torment, but the place our Lord told the thief they would meet up, in paradise. They did not wait upon the redeemer, but the resurrection of Christ. He being the first (in authority and order) of the resurrection to appear in heaven. This is seen by John when Christ took the Scroll, and in Hebrews by the blood atonement.
Forgiveness of sin relied upon blood sacrifice. The difference between animal and Christ was His was once forever.
Christ long ago shed blood for all sin as John states
2He Himself is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
Once for all.
You were redeemed at the appointed time, but the sin sacrifice was made long ago by Christ. The ancients were in the same boat, but at a different oar. At the appointed time they were redeemed, by a temporary shed blood system, yet by type, pointing to the once for all.
It brought forgiveness to you and me and the holy atoning sacrifice of Jesus took the just wrath of God away from me while placing it upon the sacrifice of Jesus that not only covered my sin for a period of time, but covered my sin once and for all.
Hebrews 9 and Hebrews 10 are of such great assistance here in understanding the connection between the foreshadowing tabernacle and sacrifices of the high priests, with the once for all sacrifice of our High Priest, Jesus Christ.
I hope this helps you understand how I am viewing scripture from God's foreshadowing in the Old Covenant to Jesus fulfillment in the New Covenant.
I agree, Hebrews is a wealth of meat that very few are willing to even attempt to digest. Most, as Hebrews pauses to say, prefer milk.
Where you assign wrath and apparently an ongoing need that present day folks somehow have their punishment imputed 2000 years ago to Christ, I present no wrath and a one time satisfactory conclusion of the sacrificial atonement in which some of all ages were reconciled to God and eventually enter His rest as saints (using Paul's description of believers).
