'Justified by Works' in the Bible

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

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

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

And likewise was not Rahab the prostitute also justified by works [when she] welcomed the messengers and sent [them] out by a different route?
