From the time of Adam and Eve's first sin, a blood sacrifice had to be made to atone for sin. We know this because G-d clothed them in animal skins. There had to be bloodshed in order to have animal skins.
No other sacrifice is acceptable to G-d. It must be a blood sacrifice.
Gen 4:3-5 "And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the L-RD. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the L-RD had respect unto Abel and to his offering: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.
In Genesis 22:1-6 A forshadowing of Yeshua offering himself for the atonement of sin.
And it came to pass after these things, that G-d did tempt Abraham, and said unto him, Abraham: and he said, Behold, here I am.
And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of.
And Abraham rose up early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son, and clave the wood for the burnt offering, and rose up, and went unto the place of which G-d had told him.
Then on the third day Abraham lifted up his eyes, and saw the place afar off.
And Abraham said unto his young men, Abide ye here with the ass; and I and the lad will go yonder and worship, and come again to you,
And Abraham took the wood of the burnt offering, and laid it upon Isaac his son; and he took the fire in his hand, and a knife; and they went both of them together.
And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering?
Well, G-d did provide the Ram, but what a foreshadowing.
Yeshua was symbolized by the Ram that was caught in the thicket by his horns. (Gen. 22:13)
Instead of Isaac, Abraham's son, G-d also provides his only son Yeshua, behind the burning (fire) bush (wood) many years later. Not only to Moses but also years later as a sacrifice for the sins of the world. Only G-d could do something so profound and awesome! G-d is not limited by time.
So, The Son appeared again. This time to John the Baptist. (John 1:29)
What did John say?
Behold, The Lamb of G-d, who take away the sins of the world.
Caiaphas, the High Priest at the time, prophesied that Yeshua would die for the Jewish nation, and not only for that nation, but for the scattered children of G-d, (Gentiles) to bring them together and make them one. (John 11:51)
G-d has always required a blood sacrifice as atonement for sin.
"For the life of the flesh is in the blood and I have given it to you upon the altar to make an atonement for your souls. (Leviticus 17:11)
For the Jewish people, G-d mandated that the blood of an unblemished lamb be sprinkled at the altar of the Tabernacle and by the sons of Aaron. (Leviticus 1:5)
Only G-d is sinless (unblemished) "For there is no man that sinneth not." (1 Kings 8:46)
Also Jewish and non-Jewish historians agree that both the Tabernacle as well as the genealogical records (whereby we could know who are the sons of Aaron) were destroyed by Titus in 70 A.D.
Has G-d left his precious people dangling in mid-air with no hope at all of ever having sins forgiven all these years since 70 A.D.? Of course not. He has not failed you or me.
He has provided for our safety. How?
Well, our own good deeds cannot purify us in the sight of G-d.
"But we are ALL as an unclean thing and all OUR righteousness are as an unclean garment" (Isaiah 64:5)
Working out our own means of salvation is a dead-end street.
"There is a way which seemeth right to unto a man, but the end there of are the ways of DEATH." (Proverbs 14:12)
How? Our safety, our refuge, is in G-d's Son Messiah.
How can his son be divine also. He has a human nature and a divine nature.
You may say,
Shema Yisroel, Adonai Elohenu, Adonai Echad.
Hear, O Israel: the L-rd Our G-d, is One L-rd.
There are two words for 'one' in the Hebrew language: 'Echad,' and 'Yachid.'
'echad' is a united one, (one-made-up-of-parts) which means several, or many in one, a composite-one.
'Yachid' is interpreted to mean absolutely and indivisibility one, ONLY one, one only and no other. 'Yachid' is used forcefully in the Bible as an absolute unity and is found twelve times in the T'nach but not once is it used to denote the UNITY OF G-D!
In Genesis 1:26 G-d said
"Let Us make man in Our image, according to Our likeness..."
The Hebrew word for G-d here is Elohim, a plural noun.
Another Foreshadowing of the amazing birth of the Messiah.
Before Isaac was born, Sarah was barren.
G-d said, Sarah your wife shall have a son.
And Sarah laughed to herself, saying, "After I have become old, shall I have pleasure, my L-rd being old also?
And G-d said, "Is anything too difficult for the L-rd?
Years later, a virgin gave birth. (Luke 1:31)
An Angel said, "Behold, you will conceive in your womb, and bear a son Ò
And she said, Ò How can this be, since I am a virgin?
And the angel answered and said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; and for that reason the holy offspring shall be called the Son of G-d.
And Miriam did not laugh, but said, "Behold, the bondslave of the L-rd; be it done to me according to your word."
And she rejoiced, "My soul exalts the L-rd, And my spirit rejoiced in G-d my Savior.
I say to the house of Israel, "Is anything too difficult for the L-rd?"
This was done because the Messiah had to be sinless.
The sin nature is passed from the father, but His Father was G-d, who is sinless.
Miriam's son, G-d's son, became her Messiah and Savior.
Messiah born of a virgin.
Behold, the young women ('almah' - virgin) shall conceive, and bear a son, and shall call his name Immanuel. (G-d with us) (Isaiah 7:14)
Messiah was slain for our sins.
He then was crucified on the tree.
Psalm 22, describes this one thousand years prior to the actual event, at the time crucifixion was unknown. (Capital punishment was stoning in David's day)
"But he was wounded because of our transgressions, he was crushed because of our iniquities: the chastisement of our welfare was upon him. And with his stripes we were healed. All we like sheep did go astray, we turned every one to his own way; and the L-rd hath made to light on him the iniquity of us all." (Isaiah 53:5,6)
"For Thou wilt not abandon my soul to the netherworld; neither wilt Thou suffer thy G-dly One to see the pit." (Psalm 16:10)
The blood of Messiah can make atonement for your sin. You can be forgiven -and KNOW it. How? The T'nach tells us:
"Whosoever shall call upon the name of the L-rd shall be delivered (saved)(Joel 3:5)
Why not pray this prayer from your heart and find that sweet assurance of forgiveness that has been there all the while for the asking.
DEAR JEWISH MESSIAH. I Now admit That I am a sinner in need of your cleansing, saving blood. I realize now that you are the perfect blood sacrifice, and that you gave up your blood freely for me.
Come into my heart and life, L-rd Messiah, And Save me and keep me
Thank you, For I Believe That You Have Done This, as YOU Said YOU Would, In the name of Messiah, Amen.
Are you now forgiven? G-d says an emphatic "Yes!"
(Joel 3:5, Daniel 12:2 & Numb. 23:19)
If you have prayed the above prayer with a sincere heart, you can now right fully claim Yeshua Ha Mashiach as your very own Savior!
You may also want to read the book of Hebrews for assurance.
Heb 9:11-10:23 - But Jesus (Yeshua) being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; Neither by the blood of goats and calves, but by His own blood He entered in once into the holy place, having obtained eternal redemption for us. For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctified to the purifying of the flesh: How much more shall the blood of Christ (Mashiach), who through the eternal Spirit offered himself without spot to G-d, purge your conscience from dead works to serve the living G-d? And for this cause He is the mediator of the New Covenant, that by means of death, for the redemption of the transgressions that were under the first covenant, they which are called might receive the promise of eternal inheritance. In the case of a will, it is necessary to prove the death of the one who made it, because a will is in force only when somebody has died; it never takes effect while the one who made it is living. Whereupon neither the first covenant was dedicated without blood. For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people, Saying, This is the blood of the covenant which G-d hath enjoined unto you. Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry. And almost all things are by the law purged with blood; and without shedding of blood is no remission. It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these. For Jesus (Yeshua) is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of G-d for us: Nor yet that he should offer Himself often, as the High Priest entereth into the holy place every year with blood of others; For then must he often have suffered since the foundation of the world: but now once in the end of the world hath He appeared to put away sin by the sacrifice of Himself. And as it is appointed unto men once to die, but after this the judgment: So Jesus (Yeshua') was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation. For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect. For then would they not have ceased to be offered? Because that the worshippers once purged should have had no more conscience of sins. But in those sacrifices there is a remembrance again made of sins every year. For it is not possible that the blood of bulls and of goats should take away sins. Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: In burnt offerings and sacrifices for sin thou hast had no pleasure. Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O G-d. Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; Then said he, Lo, I come to do thy will, O G-d. He taketh away the first, that he may establish the second. By which will we are sanctified through the offering of the body of Yeshua the Mashiach once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of G-d; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected forever them that are sanctified. Whereof the Holy Spirit also is a witness to us: for after that he had said before, This is the covenant that I will make with them after those days, saith the L-rd, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more. Now where remission of these is, there is no more offering for sin. Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus (Yeshua'), By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh; And having an high priest over the house of G-d; Let us draw near with a true heart in full assurance of faith (trusting), having our hearts sprinkled from an evil conscience, and our bodies washed with pure water. Let us hold fast the profession of our faith (trusting) without wavering; (for he is faithful that promised;)
