From their scriptures ,they were not expecting and still do not expect for God to become flesh and to die a horrible death as the ultimate sacrifice to save them from their sins.
Well, what about Isaiah 53 taken from the Old Testament?
'Who hath believed our report? and to whom is the arm of the Lord revealed?
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.
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 sorows: 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 chastisment 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 judgement: and who shall declare his generation? for he was cut 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 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: 1-12
This was prophesied in the Jewish Bible. But to come back to this point:
From their scriptures, they were not expecting and still do not expect for God to become flesh and to die a horrible death as the ultimate sacrifice to save them from their sins.
And that's exactly what happens when you accept Christ, he saves you from your sins. As Jesus himself stated in the Gospel of John: 'I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.' John 8: 24.
