Please read all the way down. The way I see it, no temple, no sacrifice required. But the law required obedience for the Jews. If the Jews have no temple, then no sacrifice required but obedience to God is required.
Ezekiel 14
3 Son of man, these men have set up their idols in their heart, and put the stumblingblock of their iniquity before their face: should I be enquired of at all by them?
4 Therefore speak unto them, and say unto them, Thus saith the Lord God; Every man of the house of Israel that setteth up his idols in his heart, and putteth the stumblingblock of his iniquity before his face, and cometh to the prophet; I the Lord will answer him that cometh according to the multitude of his idols;
5 That I may take the house of Israel in their own heart, because they are all estranged from me through their idols.
6 Therefore say unto the house of Israel, Thus saith the Lord God; Repent, and turn yourselves from your idols; and turn away your faces from all your abominations.
7 For every one of the house of Israel, or of the stranger that sojourneth in Israel, which separateth himself from me, and setteth up his idols in his heart, and putteth the stumblingblock of his iniquity before his face, and cometh to a prophet to enquire of him concerning me; I the Lord will answer him by myself:
8 And I will set my face against that man, and will make him a sign and a proverb, and I will cut him off from the midst of my people; and ye shall know that I am the Lord.

Ezekiel 14:14 Though these three men, Noah, Daniel, and Job, were in it, they should deliver but their own souls by their righteousness, saith the Lord GOD.
20 Though Noah, Daniel, and Job, were in it, as I live, saith the Lord GOD, they shall deliver neither son nor daughter; they shall but deliver their own souls by their righteousness.
The key words in the verses are “they should deliver but their own souls by their righteousness.” It is clear that they were saved by living righteous. They were not saved by the righteousness of God like Church Age Saints.
