Jesus is the proof!
Whatever other prophesies you may be referring to, none have any meaning unless Jesus is the fulfillment of the Old Testament Prophesies.
The one undeniable fact is that man is stiff necked, and rebellious. Even as children, by nature, rebel against Parental authority, it is man's nature to assert his independence, and desire full control of his own destiny.
All Scripture is quoted from the King James translation.
Beginning with Adam and Eve's rebellion in the Garden of Eden, man has continually attempted to usurp the authority of his maker.
Genesis 3:1 through 6 KJV Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? And the woman said unto the serpent, We may eat of the fruit of the trees of the garden: But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. And the serpent said unto the woman, Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil. And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
Eve was deceived, but that deceit was based on her natural instinct to be equal to God.
(Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods,)
Even though Eve was deceived by the serpent Adam was not, however, we can elicit much from Adam's Reply to God.
Genesis 3:12 And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat.
After having gained the knowledge, we see that Adam, protested his innocence while at the same time trying to make God culpable.
So now that we have established some things about the nature of man. We need to show what prophecies of the Old Testament Jesus fulfilled.
Isaiah 7:14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.
Luke 1:26 through 35 And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth, To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin's name was Mary. And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women. And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be. And the angel said unto her, Fear not, Mary: for thou hast found favour with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end. Then said Mary unto the angel, How shall this be, seeing I know not a man? And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
Micah 5:2 through 4 But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting. Therefore will he give them up, until the time that she which travaileth hath brought forth: then the remnant of his brethren shall return unto the children of Israel. And he shall stand and feed in the strength of the LORD, in the majesty of the name of the LORD his God; and they shall abide: for now shall he be great unto the ends of the earth.
Matthew 2:1 Now when Jesus was born in Bethlehem of Judaea in the days of Herod the king, behold, there came wise men from the east to Jerusalem,
Matthew 2:5 And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet,
Psalms 22:16 through 18 For dogs have compassed me: the assembly of the wicked have inclosed me: they pierced my hands and my feet. I may tell all my bones: they look and stare upon me. They part my garments among them, and cast lots upon my vesture.
Matthew 27:35 and 36 And they crucified him, and parted his garments, casting lots: that it might be fulfilled which was spoken by the prophet, They parted my garments among them, and upon my vesture did they cast lots. And sitting down they watched him there;
