"No demand."
Even before the Law God was demanding a "ransom" for sin.
Job 33:23, "If there be a messenger with him, an interpreter, one among a thousand, to shew unto man his uprightness: Then he is gracious unto him, and saith, Deliver him from going down to the pit: I have found a ransom. His flesh shall be fresher than a child's: he shall return to the days of his youth: He shall pray unto God, and he will be favourable unto him: and he shall see his face with joy: for he will render unto man his righteousness."
"Job 33:23, "If there be a messenger with him, an interpreter, one among a thousand, to shew unto man his uprightness: Then he is gracious unto him, and saith, Deliver him from going down to the pit: I have found a ransom. His flesh shall be fresher than a child's: he shall return to the days of his youth: He shall pray unto God, and he will be favourable unto him: and he shall see his face with joy: for he will render unto man his righteousness.""
Well, the Jews made all sorts of sacrifices didn't they...and not one of them gained them anything eternal, did it?
I must say, Protestant fixation with the OT and the Old Law strikes me as very, very strange. Christ gave The Church the sacraments for the forgiveness of our sins, most supremely the Eucharist which you reject. The sacraments, just like the OT sacrifices, aren't/weren't for God, they were/are for us, unless, apparently, one is outside The Church and therefore has no need of them.
Amen.
Scripture generator says...
He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not. Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all. He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth. He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken. And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth. Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand. He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities. Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors." -- Isaiah 53:2-12"For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him.
And let's not forget Christ was not taken by surprise, nor did He not commit suicide. He willingly ("for the joy that was set before Him") was put to death because God ordained Christ's sacrifice as the means to secure the salvation of His children. If He was really "the Lamb slain from the foundation of the world," then all history, all life on this planet, every atom in the universe, exists to prove that true.
"For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." -- 2: Corinthians 5:21
Who actively and knowingly made Christ to be sin? God actively and knowingly made Christ to be sin so that we could stand before Him without it.
