There is plenty that is unfulfilled. For example, the Torah predicts that the Messiah will return. That hasn't happened yet. Yet even if that was the case, do you really think that G_d wouldn't want you to honor His Law, if only out of love for Him, to learn His ways? I can tell you, the blessings and curses found in the law work almost mechanically; there is no mystery to the process at all. Yet we won't see how they work unless we follow those tenets to observe their mechanics. Don't you think we would benefit by doing things His way?
As a fellow Cruz supporter I will have to respect in how you believe, no need to get into a theological debate on who’s right or who’s wrong.
Having said that, I am not ashamed of the Gosple of Jesus Christ.
There is no other name under heaven and earth where there is salvation.
