Really that is a stretch to say all of Judaism and the Old Testament points to Jesus Christ. The majority of Jews reject Jesus. I have seen people interviewed on the streets of Israel and most make a clear distinction between Judaism and Christianity, and most reject Jesus as the Messiah.
If there is only one God then he is infinite and manifest as the whole universe otherwise he would not be God, he is not holed up within the pages of one holy book like a Genie.
Peace.
Not a stretch at all. The OT and NT point to the Messiah. The Jews envisioned a mighty, conquering king on a white horse and carrying a sword leading an army to destroy their enemies. Instead arrived Jesus Christ. A man with humble beginnings, nothing in his pockets and desire to teach, relay prophecy, perform miracles and die brutally at the hands of the Romans coaxed by the Sanhedrin.
The majority of the world rejects Jesus Christ...the jews are just a portion of that. I've seen jews, muslims, hindus, unitarians, scientologists, atheists and even some "Christians" reject Jesus Christ.
Exactly he's evident through all of his creation, through his body of believers, through the pages of history and through scripture.
