Galatians 3:23-28

But before faith came, we were kept in ward under the law, shut up unto the faith which should afterwards be revealed. So that the law is become our tutor to bring us unto Christ, that we might be justified by faith. But now that faith is come, we are no longer under a tutor. For ye are all sons of God, through faith, in Christ Jesus. For as many of you as were baptized into Christ did put on Christ. There can be neither Jew nor Greek, there can be neither bond nor free, there can be no male and female; for ye all are one man in Christ Jesus.
