The promises of God to Israel were all contingent on their obedience, otherwise you would be utterly destroyed, scattered across the 4 corners of the Earth. Hence the Babylonian captivity, and, again, the wrath of God as predicted by Jesus Christ on Jerusalem and the Temple in 70AD on the anniversary of the destruction of the previous temple, leaving some 2 or 3 million Jews dead, and many more sold into slavery. And since that time you've known no prophet, but just dozens of false "Messiahs" whom you've all flocked to, only to be disappointed again and again. And since that time you've mingled your so-called religion with the filth of witchcraft and near constant stupidities from your Rabbis, who teach you how to eat urinal cakes or that you should not pee immediately before sex, lest your children catch epilepsy.
Jesus Christ did what Israel (according to the flesh) could never do-- He kept the law, and through Him all those joined to Him enjoy the promises and love of God:
Gal 3:29 And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
Witchcraft and urinal cakes. My, my, my but you have an active (and twisted) imagination.
As for there being no Temple, any parent will punish his or her children for misbehaving. However, in the end the parent will forgive the child, particularly if the child meets the parent at least part of the way. This particular Parent has explicitly promised just that kind of forgiveness for His people, and prophets from LONG before the life of my cousin the carpenter predicted both the second dispersion of the Jews, and the ultimate redemption much later in history. That which is true is not new, and that which is new is not true.
