13 - Three Verses Misunderstood

I refer to Galatians 3:23-25, the climax of Galatians 3:10-25. I quote the verses:
Before faith came, we were kept under guard by the law, kept [literally ‘confined' – footnote] for the faith which would afterwards be revealed. Therefore the law was our tutor to bring us to Christ, that we might be justified by faith. But after faith has come, we are no longer under a tutor (NKJV).
