I hold to all of this, but I’m sorry - you’re confusing justification and sanctification. I’m happy to go through all of these verses one by one to explain how, but I think it could be easier to refer you to Romans and Galatians, where Paul talks about it in great detail.
What Paul is saying - namely, that we are justified by faith apart from the works of the Law - is not contrary to what our Lord says.
Salvation is from God alone.
Only in YHWH can man have righteousness.
Isaiah 45:21-25,“Declare and bring near, let them even take counsel together. Who has announced this from of old? Who has declared it from that time? Is it not I, יהוה? And there is no mighty one besides Me, a righteous Ěl and a Saviour, there is none besides Me. “Turn to Me and be saved, all you ends of the earth! For I am Ěl, and there is none else. “I have sworn by Myself, a word has gone out of My mouth in righteousness, and shall not return, so that to Me every knee shall bow, every tongue swear. “One shall say,
‘Only in יהוה do I have righteousness and strength’ – he comes to Him. And all those displeased with Him shall be put to shame. “In יהוה all the seed of Yisra’ĕl shall be declared right and boast.”
John/Yahanan 5:28-30, “Do not be astonished at this-for the hour is coming in which all who are in the graves will hear His voice, and will come forth.
Those who have practiced righteousness will be resurrected in order to live; and those who have practiced wickedness will be resurrected in order to be damned."
Revelation 14:12-13, “Here is the endurance of the set-apart ones, here are those
guarding the commands of יהוה and the belief of יהושע. And I heard a voice out of the heaven saying to me, Write, Blessed are the dead who die in the Master from now on. Yes, says the Spirit, in order that they rest from their labors, and their works follow with them.”
Revelation 22:12-15, "And behold, I come quickly, and My reward is with Me,
to give every man according as his work will be. I am the First and the Last, the Beginning and the End.
Blessed are those who keep His Laws, that they may have right to the tree of life, and may enter in through the gates into the city. For outside are dogs, and sorcerers, and whoremongers, and murderers, and worshipers of gods and everyone who professes to love, yet practices falsehood."
Im not a fan of galatians, Paul says James, Peter and John only appear to be pillars of the faith but do not walk according to truth of the gospel.
Galatians 2:4-14, " 4 Yet because of
false brothers secretly brought in—who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery— 5 to them we did not yield in submission even for a moment, so that the truth of the gospel might be preserved for you. 6 And from
those who seemed to be influential (what they were makes no difference to me; God shows no partiality)—those, I say,
who seemed influential added nothing to me. 7 On the contrary,
when they saw that
I had been entrusted with the gospel to the uncircumcised, just as Peter had been entrusted with the gospel to the circumcised 8 (for he who worked through Peter for his apostolic ministry to the circumcised worked also through me for mine to the Gentiles), 9 and
when James and Cephas and John, who seemed to be pillars, perceived the grace that was given to me, they gave the right hand of fellowship to Barnabas and me, that we should go to the Gentiles and they to the circumcised. 10 Only, they asked us to remember the poor, the very thing I was eager to do. 11 But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. 12 For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. 13 And the rest of the Jews acted hypocritically along with him, so that even
Barnabas was led astray by their hypocrisy. 14 But when I saw that
their conduct was not in step with the truth of the gospel, I said to Cephas before them all, “If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?”
