'Justified' in the Bible

but knowing that a person is not justified by the works of the law, if not by faith in Jesus Christ, and we have believed in Christ Jesus so that we may be justified by faith in Christ and not by the works of the law, because by the works of the law {no human being will be justified}.

But if [while] seeking to be justified by Christ, [we] ourselves also have been found [to be] sinners, then [is] Christ an agent of sin? May it never be!

Now [it is] clear that no one is justified in the sight of God by the law, because "the one who is righteous will live by faith."

So then, the law became our guardian until Christ, in order that we could be justified by faith.

You are estranged from Christ, [you] who are attempting to be justified by the law; you have fallen from grace.
