Read 2Timothy 3:15, John 20:31 & 1John 5:3

God's Word is the revelation of Jesus Christ to man.

You can even find Jesus in the Old Testament. There are various place where God showed His plan to reconcile man unto Himself through Hid Son, Jesus Christ. Here is just one example which may be found in Exodus, chapter 12:

Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for a house: And if the household be too little for the lamb, let him and his neighbor next unto his house take it according to the number of the souls; every man according to his eating shall make your count for the lamb. Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats:
Exodus 12:3-5 (emphasis mine)

And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it.
Exodus 12:7

For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the LORD. And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.
Exodus 12:12-13

For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side posts, the LORD will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.
Exodus 12:23

And it came to pass, that at midnight the LORD smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle. And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt; for there was not a house where there was not one dead.
Exodus 12:29-30

And it came to pass the selfsame day, that the LORD did bring the children of Israel out of the land of Egypt by their armies.
Exodus 12:51

Jesus is our sacrificial Lamb.
