'Works' 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}.

I want only to learn this from you: Did you receive the Spirit by the works of the law, or by the hearing of faith?

Therefore does the one who gives you the Spirit and who works miracles among you [do so] by the works of the law, or by the hearing of faith?

For as many as are of the works of the law are under a curse, for it is written, "Cursed [is] everyone who does not abide by all [the things] that are written in the book of the law to do them."
