When Peter began to separate from associating with the Gentiles, for fear of the Jews, Paul opposed him to his face. Though Peter knew that salvation had come to the Gentiles, that justification came by faith and not works, he nevertheless was acting in a way that showed the gospel was for those who kept the law; he was fighting a war that had long since been finished. In this sermon, guest speaker Jared Wilson explains the implications of keeping in step with the truth of the gospel and exhorts the church to obey this good news – to be the finished work of Jesus Christ.
