Israel is a nation - not a religion. Their religion has no significance without sacrifice. How are they to obtain forgiveness? They must either accept the sacrifice of their Messiah or sacrifice animals for atonement. If they do neither, they are without a path to peace.
What a pity!
Plenty of scripture points to the fact that they will obtain forgiveness. It’s future, yet to happen, but it will happen.
See Zechariah 12:10
John 19:37
