Not exactly correct. There was no ultimatum to repent; the Lord prophecied that the temple would be thrown down, and also that the blessings would be temporarily transfered to another nation (the church).
They did not receive the lamb of God the one and final sacrifice and continue to bring the blood of bulls and goats to God for a sacrifice and in my opinion it was an abomination to God, an abomination that God made desolate in 70 AD.
Please show me where God has abandoned Israel and has transfered the covenant blessing of Israel to the church. thanks
