" Living toward a world in which these identities no longer divide, but living in a world fundamentally structured by them, Paul takes up and lays down various identities for the sake of the gospel. Though free, he has made himself a slave. For the sake of the gospel, he lives sometimes as one under the Jewish law, other times as one free from it—all while recognizing the truth of his situation as one no longer under “the law” but nevertheless under “Christ’s law. "
