'Justified by Works' in the Bible

For if Abraham was justified by works, he has something to boast about, but not before God.

yet who know that a man is not justified by works of the law but through faith in Jesus Christ, even we have believed in Christ Jesus, so that we may be justified by faith in Christ, and not by works of the law, because by works of the law will no flesh be justified.

Was not Abraham our father justified by works when he offered up Isaac his son on the altar?

You see that a man is justified by works and not by faith alone.

In the same way was not Rahab the harlot also justified by works, when she received the messengers and sent them out by another way?
