Many Jews converted to what is now called Christianity, but they prefer to be called "Believers", as do I. The word Christian was meant to be derogatory, but wasn't to Believers.
If you notice, Noah and Abraham became justified(found favor), in God's eyes, not because they were good, but because they "believed" God.
The Bible from Genesis to Revelation is about the revealing of Jesus to the world. Either you believe He sent His Son, or God is a liar.
Jesus fulfills completely, ALL, Jewish prophesies on the subject. When Jesus said on the cross,"It is finished", It means He is done with His work. You either believe or don't. He won't beat you into submission to believe. He calls, He woos, He pursues, but He won't force.
One of the most striking stories to the Jews has to be the Story of Abraham and Issac. Who do the Jews think the lamb was that was provided by God?
The God of Israel is different from other gods in that he has no son. Zeus, for example, had sons. God has no son.
The Jewish Bible is monotheist. Monotheism means that there is a definite distinction between God and man. Men are men and God is God. No man is divine, not even the Messiah, should he ever come.
I do NOT believe that God sent his son and I do not believe God is a liar. Paul is a liar. Paul admits that he is a liar (1Corintians 9:19-22). God is not a liar.
