Corey,
Thank you for taking the time to put together a thoughtful reply to my post. I appreciate it!
Thank you, as well.
My secular education was heavily science based. And most things are taught in a way such that everything rests on underlying principles. A cannon ball travels through the air in a very particular way. Way? Well, because of momentum, initial conditions, gravity, and so on. And why do those things work the way they do? Well, because of conservation of energy, atomic structure, general relative, and so on. My point is that we learn that everything in God's creation is orderly, rational, consistent, and typically the result of underlying deeper principles.
That's good. This I like.
So when you point out all the places in the Bible where it is stipulated that Blood = life, and sacrifices of blood cover sin etc, I can't help but believe that these are all high-level symbols that represent a deeper meaning. I learned an expression once that "analogies don't walk on all four legs," which is a weird saying, but means that analogies can only go so far when explaining a truth. Not all parts of the analogies will hold up when compared to what is actually the case. And likewise, I think the symbolism of blood (i.e. plasma, RBC's, WBC's etc) for life is good, but not 100% correlated to reality.
That's cool.
There is a lot we do not understand, as humans.
If we could reach the level of God's mind... Now that would be something... but we can't.
Jesus spoke in thought-provoking parables. And this seems like a similar good one. It posits "sin" as an employer, and if you go work for this guy, you will get paid something at the end of the day. And the "wages" you will get are death.
This is true.
You seem to appreciate Jesus' illustrations as much as I do.
Matthew 26 -- 27 Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28 This is my blood of the covenant, which is poured out for many for the forgiveness of sins.
One way of thinking about this is: Jesus's blood --> sins forgiven (don't worry about the how's and why's)
Interesting thought.
As a person whose secular education was heavily science based, I know that you are interested in the hows and whys. I don't have to ask.

If you aren't, I'll have to ask why, because the two don't mesh - not being concerned with the hows and whys, and a secular education that was heavily science based.
I know what would cause a person with a secular education that was heavily science based, to "erase", or try to "erase" concern with the hows and whys, and the cause is not a good one... neither the effect.
I'm happy that I can have this conversation with you, because you understand science.
For every effect there is a cause.
I hope you agree, as I understand that some scientists seem to be bucking against causality.
I'd be happy to share with you, what the cause is, if you are interested.
However, picture the scene...
Jewish religious leaders - those versed in the law - set out to trap Jesus - a man they claim has a demon - with a question.
Jesus replied, “
Your mistake is that you don’t know the Scriptures, and you don’t know the power of God."
Mark 12:24
Can you imagine.
I would feel embarrassed - me, a teacher of law, being told, "
you don’t know the Scriptures".
Would you not be embarrassed to be told, "You don't know science." after studying it for so long... as you described it "heavily science based"?
That would not be the case with Jesus' friends, who sought to find out the whys and hows.
John 15:15;
Matthew 13:10-17
They became Jesus' friends because they were not like the masses today who all are self taught. Jesus' friends are like the little child Jesus used as an example. They wanted to be taught. They were teachable.
Matthew 18:2-4
2 Jesus invited a little child to stand among them.
3 “Truly I tell you,” He said, “unless you change and become like little children, you will never enter the kingdom of heaven.
4 “Truly I tell you,” He said, “unless you change and become like little children, you will never enter the kingdom of heaven.
Another way of thinking about this is: Understanding that Adam & Eve's betrayal ceded control of Earth to Satan and that recovery of control requires trusting and following God's instructions completely -- even if to the point of death. Jesus, taught His disciples the example by willingly choosing death over distrust of God. And the disciples were thereby emboldened to accept flogging and yet say to the Jewish rulers "We must obey God rather than men" (
Act 5:29). Sin may be considered a legal debt, but it should also be understood as a habitual propensity to do wrong. When a child scribbles on the wall with crayons, a mother can forgive the child and repaint the wall. But the ultimate goal is not forgiveness, but for the child to learn to stop the destructive behavior. The "forgiveness" given by the mother means that she takes care of the problem, as she goes to extra effort to compensate for the error. Jesus, by His death, does allow for "forgiveness" because He has taken care of the problem. He has regained a future for mankind rather than the complete extinction Satan desires. Jesus has regained control of Earth, He has shown us the way to overcome evil, and He has earned our love and respect.
I like your illustration.
The former method is the Penal Substitution theory of salvation, and what I am trying to describe in the second is more like the Moral Influence theory of salvation. I suspect it is like the blind men and the elephant -- each describing a different part of the larger whole truth.
I had to look up that term Penal Substitution, as i have never heard it in my life.
Penal Substitution declares that Christ, voluntarily submitting to God the Father's plan, was punished (penalized) in the place of (substitution) sinners, thus satisfying the demands of justice and propitiation, so God can justly forgive sins making us at one with God (atonement).
I hope you did not get that from my post, because I do not believe Christ was punished in place of sinners.
Now I understand what you are saying, and I now see the significance of your illustration of the mother and child.
So, that you know, what the Bible really teaches on that.
Man was not being punished by God. Oh wow. This is interesting. Oh boy.
Man was dying, because his lifeline to God was cut... not by him, but by Adam. Man was spiraling down to a never-ending Grave.
God threw out a lifeline. In fact, as soon as Adam severed the cord, God acted immediately (Genesis 3:15)
It was God's will to save mankind from death, and connect him to the source of life, which mankind did not know, because they were alien.
Ephesians 4:18
having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart;
Well said NKJV
Because a death occurred, the God of justice, could only repaint the wall by abiding by own principles, and standards, since everything in God's creation is orderly, rational, consistent, and typically the result of underlying deeper principles... including his own nature, which is itself a law, and highly ordered.
This is the reason "it is impossible for God to lie." Hebrews 6:18
Hence the just way to redeem mankind was to have an equivalent of perfect Adam whose blood would be able to cover the sins of mankind.
God was in effect painting the wall and forgiving the child. Not punishing it.
Paul put it simply.
1 Corinthians 15:22 For as in Adam all die, so in Christ all will be made alive.
Christ's blood is the atonement .
It's like when you have a wound, that will take time to heal. Dressing the wound will keep it free from germs, and at the same time allow it to heal.
Christ's sacrificial blood is like that dressing. Your wound will heal without leaving a scar though.

Isaiah 65:17; Revelation 21:4
I don't know if that helps, or makes a difference, but this is a subject that a lot needs to be said, to gain a clear understanding of the whys and hows... which are important, contrary to what the cause would dictate.
Corey,
I think it is safe to say that HOW God saves us is not nearly as important as the fact that He DOES save us. And ultimately we have to trust in Him. I do pray about this and I continue to research the topic.
We are told it's safe to say that Kevin.
Can I make a deal with you? If God and Jesus says it's safe to say that, and you can show me where in the Bible I can find that, and I see it's there, i will agree with you, and we can shake hands on it.
Deal?
Again, thank you so much for your kind efforts.
Best wishes
Kevin
Thank you Kevin. thanks too for your pleasantness. It was a pleasure speaking with you.
I hope we can do it again.
peace be with you.
