May I suggest that the answer is found in Deuteronomy 28.
The Jews have chosen to follow the Torah and according to Deut 28, they are blessed because of this. Many Christians on the other hand have chosen to reject the Torah based on their interpretation of Paul's writing even though Yeshua (Jesus) said in Matthew 5:17-19:
"Do not think that I came to destroy the Law (Torah) or the Prophets. I did not come to destroy but to fulfill.
For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law (Torah) till all is fulfilled.
Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven.
I tend to believe that when the Almighty chooses to say something to us, He means it and will not go back on His word.
