'Requires' in the Bible

yet we know that a person is not justified by doing what the Law requires, but rather by the faithfulness of Jesus the Messiah. We, too, have believed in the Messiah Jesus so that we might be justified by the faithfulness of the Messiah and not by doing what the Law requires, for no human being will be justified by doing what the Law requires.

I do not misapply God's grace, for if righteousness comes about by doing what the Law requires, then the Messiah died for nothing.
