The saved ones are saved because Jesus' blood alow them to be ... but everyone will be judged for their works:
Rom 2:1 (LEB) Therefore you are without excuse, O man, every one of you who passes judgment. For in that which you pass judgment on someone else, you condemn yourself, for you who are passing judgment are doing the same things.
2 Now we know that the judgment of God is according to truth against those who do such things.
3 But do you think this, O man who passes judgment on those who do such things, and who does the same things, that you will escape the judgment of God?
4 Or do you despise the wealth of his kindness and forbearance and patience, not knowing that the kindness of God leads you to repentence?
5 But because of your stubbornness and unrepentant heart, you are storing up for yourself wrath in the day of wrath and of the revelation of the righteous judgment of God,
6 who will reward each one according to his works:
7 to those who, by perseverance in good work, seek glory and honor and immortality, eternal life,
8 but to those who act from selfish ambition and who disobey the truth, but who obey unrighteousness, wrath and anger.
9 There will be affliction and distress for every ?human being? who does evil, of the Jew first and of the Greek,
10 but glory and honor and peace to everyone who does good, to the Jew first and to the Greek.
11 For there is no partiality with God.
12 For as many as have sinned without law will also perish without law, and as many as have sinned under the law will be judged by the law.
13 For it is not the hearers of the law who are righteous in the sight of God, but the doers of the law will be declared righteous.
14 For whenever the Gentiles, who do not have the law, do by nature the things of the law, these, although they do not have the law, are a law to themselves,
15 who show the work of the law written on their hearts, their conscience bearing witness and their thoughts one after another accusing or even defending them
16 on the day when God judges the secret things of people, according to my gospel, through Christ Jesus.
17 But if you call yourself a Jew and rely on the law and boast in God
18 and know his will and approve the things that are superior, because you are instructed by the law,
19 and are confident that you yourself are a guide of the blind, a light of those in darkness,
20 an instructor of the foolish, a teacher of the immature, having the embodiment of knowledge and of the truth in the law.
21 Therefore, the one who teaches someone else, do you not teach yourself? The one who preaches not to steal, do you steal?
22 The one who says not to commit adultery, do you commit adultery? The one who abhors idols, do you rob temples?
23 Who boast in the law, by the transgression of the law you dishonor God!
24 For just as it is written, “The name of God is blasphemed among the Gentiles because of you.”
Jesus' blood does not exempt anyone from their responsibility as a christian. Christians have instructions the same way jewish had. Even if salvation is not coming out of obeying those instructions, who does not obey them intentionally, won't get any salvation at all.
Compare these two scriptures, both in the same context:
Heb 10:17 (LEB) He also says,“Their sins and their lawless deeds I will never remember again.”
18 Now where there is forgiveness of these, there is no longer an offering for sin.
and:
Heb 10:26 For if we keep on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins,
27 but a certain fearful expectation of judgment and a fury of fire that is about to consume the adversaries.
There is NOT any contradiction on both declarations; both are true and so: the person who received and accept forgiveness on Jesus' blood, MUST NOT "keep on sinning deliverately ..." or that person becomes an ADVERSARY even if his sins received forgiveness the first time he "received the knowledge of the truth".
