I kinda remember something about LAWS and PENALTIES...
Not valid?
There are 613 commandments. About 1/3 of them are related to temple activities and not applicable to today. The remainder are applicable (and the vast majority are easy to do).
The penalties were for a time when there was a Temple, Sanhedrin, Beit Din, a King...a time of a theocracy.
G-d knew (obviously)that there would be extended exiles. Deut 29:21 and Hosea 3:3-5. The penalties are not as they were before as in the theocracy and the exile itself is punishment. For the last 2000 years the Jews have been severely punished, at times far beyond what is required and that is why Isaiah says: 1 “Comfort, O comfort My people,” says your God. 2 “Speak kindly to Jerusalem; And call out to her, that her warfare has ended, That her iniquity has been removed, That she has received of the LORD’S hand Double for all her sins.”
As we go now go into the period of redemption, things will be different.
Jeremiah31 1 “At that time,” declares the LORD, “I will be the God of all the families of Israel, and they shall be My people.” ...“I have loved you with an everlasting love; Therefore I have drawn you with lovingkindness. 4 “Again I will build you and you will be rebuilt, O virgin of Israel! ....They will not teach again, each man his neighbor and each man his brother, saying, ‘Know the LORD,’ for they will all know Me, from the least of them to the greatest of them,” declares the LORD, “for I will forgive their iniquity, and their sin I will remember no more.”
Ezekiel says:13 I will bring them out from the peoples and gather them from the countries and bring them to their own land; and I will feed them on the mountains of Israel, by the streams, and in all the inhabited places of the land. ....and they will not endure the insults of the nations anymore. 30 Then they will know that I, the LORD their God, am with them, and that they, the house of Israel, are My people,” declares the Lord GOD. 31 “As for you, My sheep, the sheep of My pasture, you are men, and I am your God,”
....24 For I will take you from the nations, gather you from all the lands and bring you into your own land. 25 Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols. 26 Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. 27 I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances..
.... And I will [h]place them and multiply them, and will set My sanctuary in their midst forever. 27 My dwelling place also will be with them; and I will be their God, and they will be My people. 28 And the nations will know that I am the LORD who sanctifies Israel, when My sanctuary is in their midst forever.”’”
END OF QUOTES:
So yes, the Law is forever...penalties are not as they were since there is no longer a theocracy...G-d will punish each according to his own iniquity (jer 31) IF THERE IS NO REPENTANCE...in the era of redemption Israel will be restored...The nations will see the G-d calls Israel his "own people"...something which is a promise of G-d and would be impossible if we were theologically in error. He will cleanse us and He says " I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances.And I will take the heart of stone out of their flesh and give them a heart of flesh, 20 that they may walk in My statutes and keep My ordinances and do them. Then they will be My people, and I shall be their God. The law remains...punishment will occur by G-d...until there is a restored Kingdom...sacrifices will then return...but sin will be greatly diminished through the new covenant(To Judah and Israel not the gentiles)...so we (and the whole gentile world) will be transformed by the messianic era. Not by a god-man hybrid (such a hybrid is NEVER taught in the OT) but by G-d Himself.
