@izzythepush,
Correction.
Jesus IS in the Old Testament.
He is on every page of the Bible, actually.
In Genesis, under the story of Noah, we see the promise of God to forgive humanity even from the brink of destruction.
We see Isaac and the sacrifice of a son averted, a sacrifice that is later given by God himself.
We see God in the form of a man, both in the story of Lot and with Jacob wrestling in his name of Israel, foreshadowing the future incarnation of Jesus.
The Law itself (as the letters later explain) is set up to fail, so that believers will understand that salvation comes from the personal relationship with God that is knowing Jesus, and that neither sacrifices nor written laws can save a person.
The histories clearly lead to the promise of a Savior, with the Jewish people constantly being persecuted, and the numerous instances of the Jews trying and failing to live up to God's plans.
As do the prophecies of the Messiah.
So you see, there is never any point where Jesus is not mentioned.
