Nowhere In The Hebrew Bible (Old Testament) Did G-d Ever Said His Commandment Is With Expiration Date

Obedience to His Torah is and will always be the basis of righteousness and judgment.

Not the man-made commandment that says “Believe in Jesus, that G-d raised him from the dead,” will save you.

Paul is not really trustworthy. Thus, his writings are clear rebellion against G-d. Unless you are that dumb or ignorant not to get it until this chapter of Isaiah.

“Reward For Obedience”

Hear this, O House of Jacob, who are called by the name of Israel, and who emerged from the fount of Judah, who swear by the Name of Hashem and make mention of the God of Israel — but not in truth and not in righteousness —
48:1
rather because they are called after the Holy City and they rely on the God of Israel, Hashem, Master of Legions, is His Name.
:2
I told you beforehand, and when it had not yet happened I informed you, lest you say, ‘My deity accomplished them; my graven image and my molten idol have ordained them.’
:5
You have heard it; now see it all [happen]! Now you — will you not tell it? Now I will inform you of new events, hidden things that you did not know about.
:6
They were created just now, not long ago and not before today, and you have never heard of them — lest you say, ‘Behold, I already know them.’
:7
For My Name’s sake I shall restrain My wrath; for My praise I shall withhold My anger from you, not to cut you down.
:9
Behold, I refine you, but not like silver; I have chosen for you the crucible of hardship.
:10
For My sake, for My sake I will do [it], for how can I let [My Name] be profaned? I will not cede My glory to another!
:11
Listen to Me, O Jacob, and Israel, as he was called by Me: I am He; I am the first, also I am the last.
:12
Also, My hand has laid the foundation of the earth, and My right hand has measured out the heavens; I call to them and they stand together.
:13
… Hashem loves him who does His will in Babylonia, and [shows] His arm against the Chaldeans.
:14
Approach me, hear this: From the first I did not speak in secrecy; from the time [the decree] was issued I was there. And now, My Lord, Hashem/Elohim, has sent me with His spirit.
:16
Thus said Hashem, your Redeemer, the Holy One of Israel: I am Hashem, your God, Who instructs you for [your] benefit, Who guides you in the way you should follow.
:17
If you hearkened to My commandments, your peace would [flow] like a river and your righteousness like the waves of the sea.
:18
… ‘Hashem has redeemed His servant Jacob.’
:20
They did not thirst, though He led them through parched deserts; He made water flow for them from a rock; he split a rock and water gushed.
:21
‘[But] there is no peace for the wicked,’ said Hashem.
:22

1 Hearken to this, O house of Jacob, who are called by the name of Israel, and who emanated from the waters of Judah, who swear by the name of the Lord and make mention of the God of Israel, neither in truth nor in righteousness.
2 For they are called [as being] from the Holy City, and they leaned on the God of Israel; the Lord of Hosts is His name.
3 The first things I told from then, and they emanated from My mouth and I let [you] hear them; suddenly I did [them] and they came to pass.
4 Because of My knowledge that you are obstinate, and your nape is a sinew of iron, and your forehead is brazen.
5 And I told you from then; when it had not yet come to pass I let you hear it; lest you say, “My idol performed them, and my graven image and my molten image ordained them.”
6 You have heard, see all of it; and you, will you not tell? I let you hear new things from now, and hidden things that you did not know.
7 Now they have been created and not from then, and before the day, and you did not hear them, lest you say, “I knew them.”
8 Neither did you hearken, neither did you know, nor was your ear opened from then, for I knew that you would deal treacherously, and you were called transgressor from the womb.
9 For the sake of My name I defer My anger, and My praise is that I restrain My wrath for you, not to cut you off.
10 Behold I have refined you, but not as silver; I have chosen for you the crucible of poverty.
11 For My sake, for My sake I will do, for how shall it be profaned? And My honor I will not give to another.
12 Hearken to Me, O Jacob, and Israel, who was called by Me, I am He, I am first, yea I am last.
13 Even My hand laid the foundation of the earth, and My right hand measured the heavens with handbreadths; I call them, they stand together.
14 All of you, gather and hearken, who of them told these? The Lord loves him, who shall do His work in Babylon and [show] His arm [upon the] Chaldeans.
15 I, yea I spoke, I even called him, I brought him, and his way prospered.
16 Draw near to Me, hearken to this; in the beginning I did not speak in secret, from the time it was, there was I, and now, the Lord God has sent me, and His spirit.
17 So said the Lord, your Redeemer, the Holy One of Israel, “I am the Lord your God, Who teaches you for your profit, Who leads you by the way you should go.
18 Had you hearkened to My commandments, your peace would be as a river, and your righteousness like the waves of the sea.
19 And your seed would be like the sand and those emanating from your innards [would be] like its innards; his name shall neither be cut off nor destroyed from before Me.
20 Leave Babylon, flee from the Chaldeans; with a voice of singing declare, tell this, publicize it to the end of the earth; say, “The Lord has redeemed His servant Jacob.”
21 And they did not thirst when He led them in the wastelands, He made water run from a rock for them; He split a rock and water flowed.
22 “There is no peace,” said the Lord. “for the wicked.”
